I definitely don't bother as much with the last pages of comments. They don't have time to look for the right threads to post in, I don't have time to wade through whatever it is that they're posting.

I've looked at them before though, but I noticed that there's no interesting conversations happening there (practically no responses) and what they've said has already been covered in the threaded post I've read by then anyways. It's like they're shouting out loud to no one.
