I give more advice nowadays, but when I first joined I did try to seek it. I use Reddit for laughs, since you have to sift through a lot to get good feedback. I have no used the other two, so I can't compare.
I don't know the other sites you mention but GaG for me has more of a community feel that other forums I have been on. I suppose a lot depends on type of user you are. I fly under the radar 98% of the time so have relatively little hassle on the site.
