Sure, they should, but they don't.
Adam does, on occasion--I remember when he first joined Fedora, and I suggested that he look at the forums, and he agreed. A couple of others do as well.
However, like anyone else, they have a limited amount of time, and generally, the best way to get something to a developer's attention is to file a bug report on bugzilla.redhat.com (You have to create an account to do so). While these forums are useful, they do tend to get incredibly sidetracked. I don't know if the same issue exists on askfedora or not.
I don't look at askfedora too much, I find these forums far more entertaining, and equally useful. (That's nothing against askfedora, simply my personal taste--I only use Fedora casually too, on laptops that aren't very important.)
Anyway, while I, too, wish they would spend more time here, I fully understand why they don't--there's a lot of extraneous noise here, though, to me at least, that's part of what makes these forums fun.
