It doesn't seem like a very good idea to ignore too many people IMHO. You would run the risk of repeating something that someone else posted in the same thread which is generally frowned upon. Other users would have no way of knowing whether you did it to boost your post count or if you genuinely couldn't see their (the ignored user's) response since ignore lists aren't publicly viewable.
And it's not nice -- that's worse
Only meanies with no sense of humor ignore people, I feel you Blind. Biz you say how you shouldn't have to many people ignored because you run the risk of repeating something someone else has already said! If you look at every thread on this forum and I mean every thread, you will see people must do a lot of frowning because it is all repeated sometimes with different wording but still repeating like a parrot on every thread.
