Forums slowing down?

Occasionally I take a look at the forum threads listed in my blogroll (left column here). Recently I have come to wonder if the activities in those forums are slowing down. It's just a generel impression. Of course it would be possible to analyze if my hunch is right (sort of doing some statistics). If I'm right, then I have three possible reasons. One, forum activists are mainly new early adopters - and by definition the new&early stage has passed. Two, a number of A1000 related sites have sprung up, and people go there instead. Three, A1000 is not selling very weel, so very few newcomers visit the forums.
