I know, it’s been a while! I just saw this article on the web, what do you think? I am on the fence in regards to Twitter.
a Nielsen survey reports that only about 40% of users who sign up for Twitter are still around a month later. And that’s bad news. David Martin, Vice President, Primary Research, Nielsen Online, says:
it is clear that a retention rate of 40% will limit a site’s growth to about a 10% reach figure. To be clear, a high retention rate doesn’t guarantee a massive audience, but it is a prerequisite. There simply aren’t enough new users to make up for defecting ones after a certain point.
Nielsen Online has a graph showing how Twitter is faring against the similarly hyped MySpace and Facebook social networks. Martin says “their retention rates were twice as high. When they went through their explosive growth phases, that retention only went up, and both sit at nearly 70% today.”
