Not too much. I was referred to him through a friend of mine who is a recruiter who knew I was looking for rails dev's, we still talk about him every once in awhile as possibly the oddest dev that's ever worked for me. He was a pretty good Rails developer (and passionate) and very active on the Ruby Forums, I think he was banned at some point though for some of his behavior. I remember he went on a Facebook rant regarding his ex-wife on Facebook, about how she was keeping his kid(s?) away from him and (at the time) she was the reason he couldn't return to the United States. After he got hired, he basically went to the other dev's on the github and emailed all of them telling them "he was the new lead dev" on the project. I had to take an entire day calming down the rest of the team haha.
