"Let me know how I can help" – a proposal to HN
We have build http://DoerHub.com to tackle this head on. You post whatever projects you are working on (hackers, researchers, scientists,  are are 50%+ of the community, but there are also marketers, subject matter experts, designers, etc). Examples:http://www.doerhub.com/for/doerhub (dogfooding)http://www.doerhub.com/for/robopainthttp://www.doerhub.com/for/surgery-boards-apphttp://www.doerhub.com/for/coincashcardhttp://www.doerhub.com/for/synaptorhttp://www.doerhub.com/for/securityfirstWhoever sees your project can help in little or big ways, from joining the team to becoming an advisor or a beta user. Teams are soon getting public/private collaboration tools inside projects as well.At the same time your profile shows what areas you are great at or looking for help in/learning in, example:

An app with real-time chat and serendipity matching is in the works as well. It is entirely free, we haven't made a cent with it but some amazing projects are now in beta because of our work and people who would have never ever met otherwise (a hacker and a surgeon for example) are now doing projects together. There are growing past 600+  doers already and 80+ projects as of yesterday. You are welcome to join.We don't spread it randomly. Instead we mention it only to communities of doers we respect and would want to work with and I hope you will do the same if you join in.
