How long can a forum last before every topic has been discussed at least once? New people come to the forum with new opinions, changing the forum’s dynamic, but there is a point when everything has been discussed and some members have seen all there is to see. I suspect this happens faster on a forum with a focus like the JW experience (versus a general forum) because there is only so much to discuss about JWs and the WTBTS. Of course there are current events to discuss, but you can discuss those everywhere. I also noticed that there are generations of posters. Some people joined around the same time and perhaps posters who joined together will expire around the same time, too.
So, what is the lifespan of a forum and its posters?
If this is a repeat, I apologize.
