I agree that post count is no indication of quality.
The only time I notice it - or the join date - is when someone writes something bout how much the Cellar has changed, or how great/ rubbish it's been recently.
Then it helps to know the poster's history.
I don't think anyone here really posts to add to their post count - apart from, as Cic said - as a joke.
Those that post in inconsequential threads do it because they (I) have inconsequential things to say. After insulting Cloud early on, I have come to love the Post Whore thread, so that I can post random thoughts without bothering people who aren't interested.
Foot's Nothingland thread spew recently irritated me. But only because I'd been away for four days and thanks to the celebrated Cellar thread drift I felt it necessary to read every one to check I wasn't missing anything. I wasn't. Anyway, that's died a death now.
The only other thing that sometimes bugs me is that I can't participate in Chat. And people seem to get to know eachother well there, share info and jokes and memes. Sometimes I feel like I'm missing out on a part of the Cellar. But that's probably just insecurity.
SamIAm - don't count posts. Just hang around another ten years
