This is pretty easy to see through- Dragoneer probably will host Furocity, and in return Gavin and his staff are going to run both sites for him, and write the next version of FA. What. A. Deal.
Piche will probably change nothing- his trust issues, his lack of action on critical matters, pretty much anything that would make such an undertaking successful. And Furocity's admins now have to deal with FA's userbase. I know nothing about the guy, with regards to his coding skills. But that's not what matters in this situation- knowing how to program is not enough when it comes to fixing FA, as several of our regulars know first hand.
Honestly, I'll bet the terms of the deal were as vague privately as they are publicly, knowing Piche. So assuming Furocity was about to go under, it will now die a much slower, painful, and drama-filled death than it would have otherwise.
