Your numbers are wrong for numbers of posts at least - don't know about the rest. If you are counting top level posts, I have around 60-70 for May, if you are counting comments as well, I have around 1500 - so, which is it? I know for a fact my brother (galenkp) is not posting 9 times a day, he is posting around 2 also.
