Threads are supposed to be conversations. If everyone who wants to talk about a subject just starts their own thread, everyone will be talking to themselves. That's not how conversations work. That's not how forums work.My OPINION is to TMYOB & leave everyone else free to mind their business, too.
Also, the way people interact with the forum varies. If you're interested in a subject, it's generally easier to find a productive conversation if there's just one thread. This varies with software and platform but it is generally the case that the creation of too many threads pushes active conversations off the first page where most people look to interact with the forum. That's part of the reason why we have a rule against excessive thread creation.
