Depends on the forum, I guess. Lately I've been following the developer subforum of KVR, where folks talk about filter and oscillator algorithms using math I'll never understand. Discussions there seem well-reasoned and entirely civil. I haven't really seen them talk about performance optimizations, though. And I can't say anything about the rest of KVR.
