Twitter
1. Twitter: Là dịch vụ mạng xã hội miễn phí cho phép người sử dụng đọc, nhắn và
cập nhật các mẩu tin nhỏ gọi là tweet, một dạng tiểu blog. Những mẩu tweet
được giới hạn tối đa 140 ký tự được lan truyền nhanh chóng trong phạm vi
nhóm bạn của người nhắn hoặc có thể được trưng rộng rãi cho mọi người.
Thành lập từ năm 2006, Twitter đã trở thành một hiện tượng phố biến toàn cầu.
Những tweet có thể chỉ là dòng tin vặt cá nhân cho đến những cập nhật thời sự
tại chỗ kịp thời và nhanh chóng hơn cả truyền thông chính thống.Giới hạn về độ
dài của tin nhắn, 140 kí tự, có tính tương thích với tin SMS (Short Message
Service), mang đến cho cộng đồng mạng một hình thức tốc ký đáng chú ý, đã
được sử dụng rộng rãi đối với SMS. Giới hạn về ký tự cũng giúp thúc đẩy các
dịch vụ thu gọn địa chỉ website như tinyurl, bit.ly và tr.im, hoặc các dịch vụ nội
dung tên miền như là Twitpic và NotePub nhằm thu thập các thông tin đa
phương tiện và những đoạn dài hơn 140 ký tự.

3. History
3.1. Creation: Twitter's origins lie in a "daylong brainstorming session" held by

board members of the podcasting company Odeo. Dorsey introduced the
idea of an individual using an SMS service to communicate with a small
group. The original project code name for the service was twttr, an idea
that Williams later ascribed to Noah Glass, inspired by Flickr and the five-
character length of American SMS short codes. The developers initially
considered "10958" as a short code, but later changed it to "40404" for
"ease of use and memorability". Work on the project started on March 21,
2006, when Dorsey published the first Twitter message at 9:50 PM Pacific
Standard Time (PST): "just setting up my twttr".

"...we came across the word 'twitter', and it was just perfect. The
definition was 'a short burst of inconsequential information,' and
'chirps from birds'. And that's exactly what the product was." – Jack
Dorsey
The first Twitter prototype was used as an internal service for Odeo
employees and the full version was introduced publicly on July 15, 2006. In
October 2006, Biz Stone, Evan Williams, Dorsey, and other members of
Odeo formed Obvious Corporation and acquired Odeo and all of its assets–
including Odeo.com and Twitter.com–from the investors and shareholders.
Williams fired Glass who was silent about his part in Twitter's startup until
2011. Twitter spun off into its own company in April 2007.
3.2. Reaction: The tipping point for Twitter's popularity was the 2007 South by
Southwest (SXSW) festival. During the event, Twitter usage increased from
20,000 tweets per day to 60,000. "The Twitter people cleverly placed two
60-inch plasma screens in the conference hallways, exclusively streaming
Twitter messages," remarked Newsweek's Steven Levy. "Hundreds of
conference-goers kept tabs on each other via constant twitters. Panelists and
speakers mentioned the service, and the bloggers in attendance touted it."

Reaction at the festival was highly positive. Blogger Scott Beale said that
Twitter "absolutely rul[ed]" SXSW. Social software researcher Danah
Boyd said Twitter "own[ed]" the festival.
[20]
Twitter staff received the
festival's Web Award prize with the remark "we'd like to thank you in
140 characters or less. And we just did!"

The first unassisted off-Earth
Twitter message was posted from the International Space
Station by NASA astronaut T. J. Creamer on January 22, 2010. By late
November 2010,an average of a dozen updates per day were posted on the
astronauts' communal account, @NASA_Astronauts. See also NASA
Tweetup.In August 2010, the company appointed Adam Bain as President of
Revenue from News Corp.'s Fox Audience Network. On September 14,
2010, Twitter launched a redesigned site including a new logo.

3.3. Leadership: As chief executive officer, Dorsey saw the startup through two
rounds of capital funding by the venture capitalists who backed the
company. On October 16, 2008,

Williams took over the role of CEO, and
Dorsey became chairman of the board. On October 4, 2010, Williams
announced that he was stepping down as CEO. Dick Costolo, formerly
Twitter's chief operating officer, became CEO. According to a Twitter blog,
dated October 4, 2010, Williams was to stay
[dated info]
with the company and

"be completely focused on product strategy."
[dated info
According to The New
York Times, "Mr. Dorsey and Mr. Costolo forged a close relationship" when
Williams was away. According to PC Magazine, Williams was "no longer
involved in the day-to-day goings on at the company". He is focused on
developing a new startup, but he became a member of Twitter's board of
directors, and promised to "help in any way I can". Stone is still with
Twitter but is working with AOL as an "advisor on volunteer efforts and
philanthropy".Dorsey rejoined Twitter in March 2011, as executive
chairman focusing on product development. His time is split
with Square where he is CEO, and whose offices are within walking
distance of Twitter's in San Francisco.
3.4. Growth: The company experienced rapid growth. It had 400,000 tweets
posted per quarter in 2007. This grew to 100 million tweets posted per
quarter in 2008. In February 2010, Twitter users were sending 50 million
tweets per day. By March 2010, the company recorded over 70,000
registered applications. As of June 2010, about 65 million tweets were
posted each day, equaling about 750 tweets sent each second, according to
Twitter. As noted on Compete.com, Twitter moved up to the third-highest-
ranking social networking site in January 2009 from its previous rank of
twenty-second. Twitter's usage spikes during prominent events. For
example, a record was set during the 2010 FIFA World Cup when fans
wrote 2,940 tweets per second in the thirty-second period after Japan scored
against Cameroon on June 14, 2010. The record was broken again when
3,085 tweets per second were posted after the Los Angeles Lakers' victory
in the 2010 NBA Finals on June 17, 2010, and then again at the close of
Japan's victory over Denmark in the World Cup when users published 3,283
tweets per second. When American singer Michael Jackson died on June 25,

2009, company servers crashed after users were updating their status to
include the words "Michael Jackson" at a rate of 100,000 tweets per hour.
Twitter acquired application developer Atebits on April 11, 2010. Atebits
had developed the Apple Design Award-winning Twitter client Tweetie for
the Mac and iPhone. The application, now called "Twitter" and distributed
free of charge, is the official Twitter client for the iPhone, iPad and Mac.
From September through October 2010, the company began rolling out
"New Twitter", an entirely revamped edition of twitter.com. Changes
included the ability to see pictures and videos without leaving Twitter itself
by clicking on individual tweets which contain links to images and clips
from a variety of supported websites including YouTube, Flickr, as well as a
complete overhaul of the interface, which shifted links such as '@mentions'
and 'Retweets' above the Twitter stream, while 'Messages and 'Log Out'
became accessible via a black bar at the very top of twitter.com. As of
November 1, 2010, the company confirmed that the "New Twitter
experience" had been rolled out to all users.On April 5, 2011, Twitter tested
a new homepage, as well as phasing out the "Old Twitter. However, a glitch
came about after the page was launched, so the previous "retro" homepage
was still in use until the issues were resolved. On April 20, 2011, the new
homepage was reintroduced, though the "Switch to Old Twitter" option is
still available to users.
4. Features: Twitter has been compared to a web-based Internet Relay Chat (IRC)
client. Tweets are publicly visible by default; however, senders can restrict
message delivery to just their followers. Users can tweet via the Twitter
website, compatible external applications (such as forsmartphones), or by Short
Message Service (SMS) available in certain countries. While the service is free,
accessing it through SMS may incur phone service provider fees.Users may
subscribe to other users' tweets – this is known as following and subscribers are

known as followers

or tweeps (Twitter + peeps). Twitter allows users the ability
to update their profile by using their mobile phone either by text messaging or
by apps released for certain smartphones / tablets. In a 2009 Time essay,
technology author Steven Johnson described the basic mechanics of Twitter as
"remarkably simple:" As a social network, Twitter revolves around the principle
of followers. When you choose to follow another Twitter user, that user's tweets
mt_20110709 Page 6
MyThink
2011
appear in reverse chronological order on your main Twitter page. If you follow
20 people, you'll see a mix of tweets scrolling down the page: breakfast-cereal
updates, interesting new links, music recommendations, even musings on the
future of education.
4.1. Messages: Users can group posts together by topic or type by use
of hashtags – words or phrases prefixed with a "#" sign. Similarly,
the "@" sign followed by a username is used for mentioning or replying to
other users. To repost a message from another Twitter user, and share it with
one's own followers, the retweet function is symbolized by "RT" in the
messageIn late 2009, the "Twitter Lists" feature was added, making it
possible for users to follow (as well as mention and reply to) lists of authors
instead of individual authors. Through SMS, users can communicate with
Twitter through five gateway numbers: short codes for the United States,
Canada, India, New Zealand, and an Isle of Man-based number for
international use. There is also a short code in the United Kingdom which is
only accessible to those on the Vodafone, O2

and Orange


networks. In
India, since Twitter only supports tweets from Bharti Airtel, an alternative
platform called smsTweet was set up by a user to work on all networks. A
similar platform called GladlyCast exists for mobile phone users in
Singapore, Malaysia and the Philippines.The messages were initially set to
140-character limit for compatibility with SMS messaging, introducing the
shorthand notation and slang commonly used in SMS messages. The 140-
character limit has also increased the usage of URL shortening services such
as bit.ly, goo.gl, and tr.im, and content-hosting services, such as Twitpic,
memozu.com and NotePub to accommodate multimediacontent and text
longer than 140 characters. Twitter uses bit.ly for automatic shortening of
all URLs posted on its website.
4.2. Tweet contents : San Antonio-based market-research firm Pear
Analytics analyzed 2,000 tweets (originating from the US and in English)
over a two-week period in August 2009 from 11:00 AM to 5:00 PM (CST)
and separated them into six categories: Pointless babble – 40%,
Conversational – 38%, Pass-along value – 9%, Self-promotion – 6%,
Spam – 4%, News – 4%. Social networking researcher Danah
Boyd responded to the Pear Analytics survey by arguing that what the Pear
