A guest post by Robert J. Moore, CEO and co-founder of RJMetrics, on Engadget throws up some pretty interesting, but by no means surprising, results of a research on Twitter. Here are some excerpts :

• Twitter’s user growth is no longer accelerating. The rate of new user acquisition has plateaued at around 8 million per month.
• Over 14% of users don’t have a single follower, and over 75% of users have 10 or fewer followers.
• 38% of users have never sent a single tweet, and over 75% of users have sent fewer than 10 tweets.
• 1 in 4 registered users tweets in any given month.
• Once a user has tweeted once, there is a 65% chance that they will tweet again. After that second tweet, however, the chance of a third tweet goes up to 81%.
• If someone is still tweeting in their second week as a user, it is extremely likely that they will remain on Twitter as a long-term user.
• Users who joined in more recent months are less likely to stop using the service and more likely to tweet more often than users from the past.

I’m glad for others that they have found yet another social networking tool in Twitter. Speaking for myself, if a post needs more than 140 characters, it shows up here, else it goes on Twitter. Since the blog has a higher readership than my Twitter feeds, I do want to post my Tweets in posts periodically, but with the sheer volume of them and formatting issues while copy-pasting, I have been putting it off.

I don’t use Orkut or Facebook, so it is no surprise that I don’t see Twitter as a social networking tool. I like to keep it as impersonal as the blog, if not more.

But to each his own. If you want to share every detail of your life, go ahead and do it anyway.
