It's still pretty early in the morning around here. Give people a chance to get going in the morning. I looked at your last two posts and they just haven't been viewed by very many people yet. Generally you will get one reply for every 20 or so views or something like that. So actually how many replies you have gotten isn't unreasonable particularly considering the time differences. It isn't that no one cares, but people can only respond to the posts they read and not that many people have read your posts yet. Give it time.
