I find it amusing that after a couple of months of not doing more than 3 or 4 posts in any one day (and usual only 0 or 1), the day after the limits thing comes up is when I decide I have stuff to say (you might not agree with me ;).
If I were inclined to care more, I'd ask this directly, but what sorts of evil things do people do with over posting? When I read the post about the daily limits I was a bit surprised as it sounds like there is some really annoying stuff that happens on a regular basis when people go out of control posting. I suspect that the limits might go over better if Brad indulged our geeky natures and actually told us what problems the limits were supposed to prevent.
For the record, if anyone ever sees me approach or hit the daily limit for permanent members, please pry me away from the computer and unplug the cable modem ;)
