Are there things the community can do to help sustain things here? I'd love to contribute code but it seems like there's no open source or apps API (correct me if I'm mistaken). Other ways to help?
We are working on a number of things with the goal being a functional API, improved search capabilities and a more robust tagging system with suggested tags etc. As for how you can help now? Continue to invite your smart friends and online amigos to Hubski. Evangelize, to the right people, what you have seen here. Go rinx, spread the gospel of Hubski so that others might live meme free lives. :) Glad you found us! Let me know if you have any questions about the site etc.
Yeah, if there was an API, I'd be all over some app making. I got some cool ideas, but I guess I'll have to wait and see if they pan out.
