I noticed that before the purge, and still somewhat after, a lot of threads with just a couple questions were labeled [H], Misrah's queen strategy as [G][Q], among others. In my opinion, many strat forum threads are mislabeled these days.
The most glaring problem is the lack of [I] threads. If you have a new strategy, its [I]! If you're the only who who's used it, you can't expect [G] to be reasonable. If you think you've come up with some way to pwn newbs, don't write [Q] and ask if it will work. Write [I], its for new ideas that are (for the most part) currently obscure.
PS - Not saying everyone's done this, but just saying [I] threads are rare, although there are a lot of threads that could be named.
If you're asking about a specific game issue from a confusing game you played, such as "what did I do wrong with this slow push?", its [H]. If you're wondering about a specific issue of general play such as in progames or a common idea, its [Q]. If you have significant experience in an area and are writing informatively about it, its [G]. If you've come up with a new idea you've only tested a couple times but you think might be a decent strategy, its [I].
