I would have to agree with Mass. There is always a dangerous possibility that people with more posts will be perceived to be more Yoda like than those with lesser posts.

Take myself for instance. I have been reading this forum pretty much from the start, but I have less then 100 posts. Yet people who have joined a few months have a couple of hundred of posts talking about how great the latest loopy banger is or discussing yet again Jeff Mills' ability/inability as a DJ.

It really says nothing about your knowledge on music or life in general. The Little Detroit forum don't have any post count at all, and I think it's a great idea.
