I think, Assembly.com [1] could be characterized as "Github for Startups": different people were collaborating on projects and getting part of projects' ownership as compensation.
In my opinion, the concept was quite interesting. And thus I'd like to ask you. Have you ever used Assembly.com? If not, why? What exactly didn't you like about it (was it the idea or implementation details)?
Complaints I've extracted from other discussions on HN and Reddit so far:
1. 10% commission
2. Projects are available for authorized users only
3. The way "shares" are divided.
