Don’t worry too much about what category you post things in. You basically can’t go wrong by picking the “Usage” category as long as your topic is related to usage of Julia. Worst case, somebody with elevated discourse power-levels will come along and move it elsewhere for you. 
One piece of advice I’d give is to be specific as to the problems you’re having and what you’re trying to figure out. The never-ending IDE topic of doom might not have gone off the rails so much if you were a bit more specific about what exactly you meant by e.g. “simple”. But then again, this forum loves talking endlessly about editors, so we might have spiraled it out of control no matter what you did.
