Fair enough this will help allot of people with immediate issues.
I guess my main concern is on the number of comments/replies/post a minnow may do in one sitting..From what I can see I agree with the logic of everything else the Witnesses/Dev's are doing, but I think in stopping bad behaviors it might hurt the new people coming in (which could inadvertently have the opposite effect to all the good coming from these changes). I believe it's just a tweak (they need alittle more) and would be gold :)
