I'm a hobbyist. No more. No less. I do this because I like to - nay, because I love to! Maybe someday I'll design a game or write a book, but for now I worldbuild just to give my imagination and fingers something to do. It makes use of an anthropology education I don't otherwise feel gets made use of.
I have been posting my links and favorites and tools and goodies with the hope that someone stumbles across them and can use them. We geeks like to pay it forward and network - despite the stigma of having a complete lack of social skills. That being said "successful" worldbuilding is as much about education, imagination, and connection as it is about timing, luck, and incredible discovery.
The point I'm rambling along and trying to make is, CHECK THIS OUT! You must, your world(s) and imagination need it, demand it, and will thank you for it. Once you finally do you will kick yourself for every moment you knew of it and didn't listen.
My buddy Nils over at Enderra.com has linked to the phenomenal (but sadly over and done with) podcast Shakespeare & Dragons
I'm only on Episode 4 and it's completely blowing my mind! I'm sitting here mapping and doodling as I listen and Episode 3 alone gave me a glorious headache from the sheer volume of information and concepts and suggested exercises. Needless to say, I will finally proceed to check out on Amazon.com with Guns, Germs, and Steel that's been sitting in my cart for weeks.
