unboring

I think these are used more for PM interviews. I interviewed there once and was asked to design an evacuation plan for Manhattan (not San Francisco). I've also heard from employees there that such questions were preferred for PMs rather than engineers.

x.com was originally PayPal, so eBay owns the domain once they acquired them.

Or a Scion dealership. I bought a Scion TC a few years back and it was the smoothest experience ever. No haggling, just pay the advertised price and walk out. Every Scion dealer was obligated to advertise the same price, so you knew you were getting the same price as everyone else.

Seems like you want a system based around topics or interests. Have you tried StumbleUpon?
