When Twitter made its first big appearance (at SXSW Interactive in 2007), it was a relatively small community of techies and web 2.0 geeks. Now it's mainstream and keeps growing at an explosive rate.
HubSpot, the developer of Twitter Grader, just released its "State of the Twittersphere" report. The report reveals that an estimated 5,000-10,000 new Twitter accounts are opened every day. According to the study, Twitter appears to be most popular in major English-speaking cities. The top 5 Twitter cities are London, San Francisco, New York, Chicago, and Los Angeles.
Also, not surprisingly, the Twittersphere has a long tail:
- Only 0.8 percent of all Twitter users have more than 1,000 followers.
- Five percent have more than 250 followers.
- 24 percent (the largest group) have between 11 and 25 followers.
- Three percent of Twitter users have ten or fewer followers.
- 22 percent have five or fewer followers.
- Nine percent of Twitter users follow no one at all.
Other interesting findings:
- Twitter is dominated by newer users: 70 percent of Twitter users joined in 2008.
- There is a strong correlation between the number of followers you have and the number of people you follow.
- The most popular days of the week to tweet are Wednesday and Thursday.
