An In-Depth Exploration of Twitter

TwitterOver the past five months, Twitter has seen tremendous growth and, in the process, attracted a huge amount of media and blog coverage.

To quantify this growth, Sysomos decided to conduct a study that involved collecting information from 11.5 million Twitter accounts. We believe it’s the most extensive look at Twitter ever done, offering in-depth insight into Twitter’s growth and how people use it.

Among the findings are that:

• 72.5% of all users joining during the first five months of 2009.
• 85.3% of all Twitter users post less than one update/day
• 21% of users have never posted a Tweet
• 93.6% of users have less than 100 followers, while 92.4% follow less than 100 people.
• 5% of Twitter users account for 75% of all activity
• More than 50% of all updates are published using tools – mobile and Web-based – other than TweetDeck is the most popular tool with 19.7% market share.

The complete report on Twitter can be found online on our Web site, as well as a PDF version for download. A complete list of all graphs and charts, in addition to those in the main report, are available in the appendix to the Inside Twitter report.
