Separate LS users into categories will help nothing! I think the site is quite complete and has plenty of information (specially the forum section). What should change is the lazyness of some people. A lot of the repetitive questions are already answered in the "important topics" right at the top of every section, but people don't care to read it.
I use LS for about 5 years and sometimes, in many ways, I can't say if I'm a noob or not, so if there's two foruns, I'm gonna have to read them both. Anyway, it's just my opinion ;)
