Since Make posted about it on Saturday we've had over 45k unique views, and over a thousand people have signed up. I'm the only developer on this and am struggling to keep up with everything that's going on. In a few days when all the noise dies down I'm going to have to do a post-mortem, and I think then I'll really be looking for advise from people here on how to proceed on such a large project alone without funding.
@eugenejen - I'd love to do circuit simulation with it, but that is all a bit beyond me mathematically though I'm sure there are good resources out there to work from. We're definitely aiming to do meta tags, and hopefully since we parse the schematics into XML documents we can search within schematics as well for components.
