I would definitely second this. I have never contributed to a Haskell project, so didn't mention it in my main reply, but I was nothing short of astonished and humbled by my experience with the Haskell community when I was learning it. I've never encountered any other community that was so welcoming and willing to bend over backwards for newbies. I honestly felt a little bit bad. I grew up online, and I consider myself skilled at integrating with established communities, being polite and reserved and not expecting to be accorded unearned respect and the like. But after just asking a couple questions in the Haskell IRC channel, I found people willing to have extended in-depth discussions with me even though I was a total unknown. I didn't feel deserving of such an investment of their time and I have never come across it before or since. I consider the Python community to be excellent in my experience, but Haskell is truly god-level tier. They changed what I even thought was possible for a programming language community.
