I love #1. My personal goal is to I work on something I'm deeply attached to that's also insanely useful. I want to wake up to the sound of my phone exploding with customers pleading me to get my service back up not only because demand is toppling our servers but because my service is something those customers absolutely need every day. Don't get me wrong, I'm not asking for scaling issues or to be Techcrunched. I should be so lucky to have scaling problems working on something I love.
#4 is approaching the same thing from a different perspective. It's still a worthwhile question but I would put it under #1.
