Well I posted quite a bit when I first got here in Feb, because i was so happy to be back. My original account was banned for understandable reasons back in 2009 or so, I don't really remember. So I remember my average post count in the first month after I joined was like...26 or 30? something like that. But now it's about 15.
And Vegetarian Zombie, I have one thing to say about your post count. Considering you've been around half the time I have (actually, all in all, you've been around a small fraction of the time I have) and yet have twice the posts I have: Quality over quantity. Many of your posts lack grammar, punctuation, or any meaningful purpose. I've found myself to be typing out 3-4 loving paragraphs to elaborately respond to somebody, give feedback, or discuss something.
