I personally don't like Stack Exchange. It seems like the vast majority of the time I find going there (as a result of googling my problem) the question is closed with no answer.
I much prefer Daniweb. Newgrounds also has a pretty good Flash/Programming forum.
Kongregate's programming forum is also pretty good, I feel like it has the 'advanced' stuff while AG has a lot more 'beginner' stuff. Not all the time though, obviously.
