maybe it is just because I'm a "uu c&c person" but I see no reason for splitting the forum into OU and other.
I presume the reason that ou is the main forum in stark mountain is a combination of (a) OU is played the most on shoddy battle and is the standard tier for tournaments and whatnot (b) the main forum would not have much discussion without OU and that looks horrible for a metagame flagship forum (c) tradition.
none of those reasons apply in the QC forum. (a) UU is the most active tier in QC. out of all threads started on or after may 17th (the day phil made the "rules of qc" thread)... in the QC forum, there are 16 OU threads, 35 UU threads, 4 uber threads, and 10 LC threads. in their respective tier forums, there are 10 OU threads, 13 UU threads, 6 uber threads, and 19 LC threads. there have been 8 OU analyses, 9 UU analyses, 0 uber analyses (DEAD TIER LOL [jk]), and 7 LC analyses uploaded. (b) the second point is not very relevant since QC is not "supposed" to have the "prestige" that stark mountain has; plus, OU is not the most popular tier in QC (no tier dominates QC to the extent that OU dominates shoddy battle). (c) there is none.
C&C has a precedent for splitting forums up by tiers - because the tiers are relatively close to each other in activity and because it makes sense from a workflow perspective. I don't see a problem with a, say, uber QC subforum that has a low number of threads (just picking uber cause it has the least # of threads in QC currently)... it's not supposed to be a discussion heaven or what we point to when we tell people "look this is the heart of smogon pokemon discussion". it gets all the people who want to look at uber analyses to the right place and they don't have to subconsciously skim through tiers they don't care about.
to be clear I am advocating a full split into all the respective tiers. I guess these could all go under QC or we could make a QC subforum for every tier (the latter would require a bit of mod permissions fixing for QC people but nothing serious at all). I don't really have a preference for which way that goes.
re: more members. take... flareblitz for example. he wasn't on QC at the beginning of the program and he also wasn't a hotshot C&C contributor. but he is good at playing pokemon and also good at expressing his beliefs for why certain things should be the way they are. he posted in QC threads as a regular member then (I didn't decide this) I assume heysup/phil decided "hey this guy is smart and is contributing and we could use him - okay he's on the team!" no real application needed; just proof that he can do the job well. the rules for QC say that non-self-nominations are accepted too, so if a QC member doesn't "scout" you someone else can. I don't really know what such an application would entail anyways... I'd even argue that the most important part of QC is not phenomenal "traditional" pokemon skills but rather an amalgamation of open mindedness, pokemon skills, theorymon ability, activity, communication / logic / argumentation skills, etc... [also if we really wanna discuss the # of QC members a C&C thread is probably a better place for it since it has greater visibility for the target audience]
