There have been over 100 posts between the last time you posted (not counting this time) and now. I wouldn't exactly call that "not much going on".

Sometimes a post attracts many responses, sometimes it does not. Sometimes it's due to lack of interest and other times it's just that people don't have anything to add to the discussion. I know that oftentimes I might find an issue interesting but since someone has already expressed my point of view, I have nothing to add to the discussion and choose to keep quiet instead. Don't be discouraged by a lack of responses, each response you do get may in fact represent the feelings of a dozen different people who chose not to chime in since someone already said what they would have said.

Having said that, there is nothing wrong with participating in other forums. There are many forums out there and if you try enough of them, you are bound to find several you like.
