Well obviously if the content of the post is bad, then my opinion of the person will further drop. However, if I don't have any other way to base my opinion on the person, I usually just stick with a lower post count merits lower respect. That's only if I have nothing else.

If a person join the forums and has great ideas and discussion and perhaps starts a few good threads, then, whether he has 100 posts or 10,000 posts, I will view him/her as an intelligent individual more than I would view someone without that advantage.

What is it they say about silence being golden?
