Nice presentation? What tool do you use to builded? D3.js from scratch or another one?

yep, it's built on d3.js with custom animations and transitions

"pseudo-company" only if that means be a YC Backed non-profit organization.

Hi Sam, I've been working in my Startup since December, with my co-founder and even we win a local entrepreneurship contest about ideas and innovation. We're very confident about our idea and we have a working prototype, but, we're in the travel industry and we aren't generating any revenue yet, should we apply to Y Combinator? Even if we aren't generating any bucks?

Thanks! I think in a job search will be great! Because there's a lot of rails app over there and they always looking for RoR developers.
