To be totally honest, I am finding the sniping; condescending and snippy remarks that some posters make (and it's pretty much the same posters, no matter what thread they're on), really off putting. There have been so many threads that I've contributed to but then, when the sarky remarks get rolled out, I just leave the thread and move on. I don't want to read demands for "evidence" to back up a posters views or those dreaded endless url links; they don't contribute to a discussion, they become lectures and, imo, make boring reading, even if I'm interested in the subject. I don't think I'm alone in thinking this because I've noticed that, very often, many posters also stop posting their comments on those threads and it ends up with just one or two left who are in total mutual agreement which isn't really much of an open discussion! A good discussion is one where everyone voices their opinions but they have the good manners to respect other points of view without resorting to making anyone feel unwelcome or uncomfortable.
