This morning, we released our third State of the Twittersphere report, which shows a significant decline in the growth of Twitter users but also indicates the average Twitter user is more engaged.
The report discusses that Twitter user growth slowed from its peak of 13% in March 2009 to 3.5% in October. While 3.5% is considered successful growth for most Web applications, it's still quite a drop from Twitter's March growth. In addition, Twitter is also experiencing a decline in traffic to Twitter.com, as reported by ComScore, Quantcast.com and Compete.com.
Although Twitter's growth may be slowing, the average user appears to be more engaged than before, as is apparent from the following changes:
Today the average Twitter account has 300 followers; in July, it had 70
The average account now follows 173 accounts; in July it was only following 47
The average account today has posted 420 updates; in July that number was 119
The January 2010 State of the Twittersphere reports growth rates as calculated using the account creation data from over 5 million Twitter accounts. This data is platform agnostic -- it is the same regardless of the application the user uses. In contrast, measure of traffic on Twitter.com does not include the considerable use of Twitter via third-party applications such as TweetDeck.
