What's funny though, is that I want to contribute, but I'd rather contribute in a more tangible way: i.e. buying her the laptop or plane ticket rather than just putting money in the communal pot. For some reason, it'd make my contribution feel more meaningful, more tangible. Like if she ends up building a kickass startup 10 years from now, I'd get to say "Oh yeah, I gave her her first laptop!" rather than "Oh yeah, I gave her 50$ via indiegogo".
Maybe there's room for such a model: a kickstarter style website where individuals who need specific hardware/goods can get them purchased by third parties.
Just musing around here.
