For the past 1 1/2 years I've been maintaining a word document that contains links to resources that I've found useful. I've managed to email it to my co-workers and a few friends, but it has become cumbersome to maintain it this way.
I found a great open-source wiki platform called ScrewTurn that I'm now using to maintain this resource list. Let me know what you think - and if you have any additional resources to recommend, let me know!
