I've begun to learn playing go. It's kind of hard to find people willing to play though.
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.
