Further to my previous post now I'm not in such a rush. I don't like the PC+1 replies whether it's "+1", "This", "tbh" or anything along those lines but I'm not convinced that it is one of those things that should be restricted. If I don't think I can add anything beyond what is already there then I frequently won't post at all because I just don't see the point, my added support in the form of a +1 for a post where someone has summarised my views on the subject succinctly doesn't mean much - the post should be able to stand on it's own anyway and if it can't then it's probably not such a good point to begin with.
