I like the suggestions of having a delete button and removing the post count (at least don't display it with every post). I don't think posting frequency needs to be "rewarded". Ideally, we should reward quality (at least in the more serious topics), but voting mechanisms on most sites don't really seem to work that way.
I think a lot of the more serious discussions would benefit from having less posts in them that don't really add much to the conversation. It might be beneficial to force people to read all previous posts in a topic before responding for instance (that might be hard to implement, but counting the number of words in a topic and dividing by a fast average reading speed can give a minimum time you have to spend looking at a topic before you can post).
Then again, this is an entertainment forum, so most conversation is going to be frivolous. The captchas can really go die in a fire though.
