The orginal chart posted on this thread shows "average per day". One day I happened to check, a member posted over 60 posts IN ONE DAY, but later noticed that the member doesn't post over 40 on most days.
I guess if you get tired of reading a member's posts, you can block all posts from that member on your home page settings. I do like to check most all of the topics - some days it takes a lot longer than others - even when not very much is actually being said.
