A large percentage of our userbase is not active. A large number were never active, some weren’t even human, and many have left.
Out of the 25,302 people who have written an answer, only 3,684 have ever made to 100 lurve. Out of those 3684 people, 1244 have either left or not yet made it to 250 lurve.
If you pick 500 lurve as the benchmark for a user that has been active on Fluther for some point in time, then 1720 would qualify, not the 25,000 that have written an answer. An even better metric for a solid userbase of regular users would be those who have reached 5000 lurve: there are only 433 people who have made it to that point.
While we may have had 25000 “users”, only a couple hundred of them have stuck around for a substantial amount of time.
