That's why we've built http://DoerHub.com . We have hackers, entrepreneurs, surgeons, PhDs, and doers of all kinds posting and contributing to projects. The purpose of the site is to enable everyone to share what they are working on and grow it with help from others who care about the same topic (teammates, advisors, beta users, feedback, single-task contributors, word of mouth, you name it ). You can already message anyone, but we're adding group chat and anything else doers request that makes collaboration easier. You can just connect with GitHub.
