It always amuses me to see people making posts to the effect of, "There's no need for a thread like this", or, "Here we go again, discussing (insert anything here)".
It's a forum, folks. I can't see how it REALLY harms anyone that badly to have to scroll past a post that isn't pertinent to their interests. I can't think of a single time that I have made a post here that I actually cared if everyone was interested in the topic.
Don't like it? Keep on scrolling. When you comment on "pointless threads" and topics that weary you, you are kind of participating in and bumping the topic that you don't care about.
Just pointing that out. Carry on.
