I really think it's sort of silly to do post counts, a lot of posters post comments that don't really contribute to the thread like 'I LOVE IT!!!' when 50 other people before them already said the same thing (not that that's a bad thing!), but I personally tried to keep my posts longer to at least give a little contribution or in the very least express my opinion and give a reason why I like/dislike something.
For example, in college they tried to make you do essays or papers with a word count, and honestly I just created a situation where people wrote in a more wordy manner than usual.
This is so off topic. Yes that's true, but if they don't keep count of the post, they would have to read the posts made by everyone who wants to join the MP... Oh, I did that at school too.
