Not being a Guru, I couldn't say.
A lot of flex developers are busy on their own projects, so aren't sitting around trying to solve other peoples problems.
That said, the way a question is asked often has a lot to do with whether anyone responds.
Has this question already been answered and could the poster solve this with five minutes on google?
Is the poster demanding a quick solution to their problem?
Is the problem very specialised?
Would giving an answer involve a lot of hand-holding many developers dont have time for?
You have a response!
Well said, I'm happy that you take such a keen interest !!!
If I could upvote pauland's answer I would.
But that said, I spent a lot more time on StackOverflow these days than these forums.
