Ello, a social network that assures an ad-free experience, lept into the spotlight last week, and currently claims to process between 40,000 and 50,000 invite requests per hour. But is it doomed to make its exit just as quickly?

Not so, according to RJ Metrics. The web analytics company collected a sample size of 160,000 Ello users and crunched the numbers Thursday.

The most interesting finding is this: that six days after signup, 25% of users are still active. Thirty-six percent of users have never posted, while 27% have posted three times or more. That may not seem like a lot at first, but RJ Metrics observed that this percentage of active to inactive is comparable to Twitter’s user activity rate.

Back in August, Ello had a userbase of about 90. Now, CEO Paul Budnitz says, the site is doubling in size every one or two days. At that rate even RJ Metric’s massive sample size won’t be accurate for long. The story of Ello is still being written.
