Probably we are too few members to reach "critical mass" for a forum focused on a single topic. Not everyone has to say something new about an issue every day, which results in too few interesting posts. For me another reason to check the forum less and less frequently is that I am convinced I am currently dancing on too many parties although I lack the time for it. But this is a personal matter and not really connected to Simmetry being what it is. Anyway, I will continue to visit Simmetry (infrequently).
