So you're right, man. Even when things are looking up it can sneak up on you. I can only imagine what this poor guy went through. He set out to raise $10,000 and exceeded it by far in under 2 weeks, gets thrown into the startup spotlight, the pressure gets intense, and all the while he probably had the mindset of someone doing something much smaller. Not to assume what his thoughts were but it seems like he was just trying to something small and cool and it grew far larger than anyone had anticipated so fast that wasn't enough time to adjust and them that depression snuck in there and now he's gone.
It's so sad. I wonder if the lightning fast growth of Diaspora had anything to do with it. I wonder what effect being in the spotlight can have on someone unprepared for it.
