I blame user groups for my post count being as high as it is. I believe I have 1,200 posts in the forums.
But I don't really look at post count all that much. I respond to a post that interests me, nothing more. I don't really pay attention to the posters themselves, (post count, join date or otherwise) unless it's someone I have become forum friends with.
I am not blind, however, to the fact that higher post counts do equate to more "forum respect" as it were. I was rarely quoted before I hit about 200 posts. And I don't really think my posting style changed all that much between my first 200 and now. I also noticed an increase in quotes by random people after I hit 1,000 posts.
Again, I don't think my posts have changed, but I do think that the unfortunate truth is some people only read the posts of high post count posters. It's too bad really. I read most of the posts in the threads that interest me, and new members or low posters are just as likely to have thought provoking posts as senior members, imho.
