You may know about this, but http://gokgs.com is an active online community. I don't think I've ever had to wait more than a few minutes for a match against someone similarly-ranked (my own rank's been anywhere between 15 and 25 kyu).
I don't know how easy it is to learn there, though. Playing offline, there's usually a stronger player around who can notice specific mistakes that I make and explain them to me after the game. ("You're being too submissive", "this is bad shape - play here instead".) Without them, I imagine I'd still find out what works, but I would improve much more slowly.
