Twitter Quitters a worry

According to a study by Nielsen Online more than 60 percent of U.S. Twitter users fail to return the following month. This suggests that Twitter’s audience retention rate, or the percentage of a given month’s users who come back the following month, is currently about 40 percent.

According to the study, Twitter is still fledgling and some other sites that eventually lived up to Twitter-like hype suffered from poor retention in the early days. When compared with early days of social networking heavy weights like Facebook and MySpace, 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 percent today.

So is Twitter worth all the hype?
