Everyone here might think I sound crazy but giving other people the opportunity to help other people is about the most rewarding thing a human can do. You have start up experience, help other start ups looking to help mankind get on their feet. You'll start a chain reaction. You can be as idealistic as you want, but on one condition. Don't ever invest more than $20,000 per person. You want to get someone on their feet so they can get 2 other people on their feet and so on and so forth, you don't actually want to invest.
As an Assembla user I fear they are not focusing on their core product. They have some weak areas in Assembla I wish they would focus on instead of reinventing the wheel.
