I saw your recent complaints about the absurdity of programming challenges during job interviews. It is very silly making a someone write an algorithm on a whiteboard to measure his/her ability. What techniques do you use to evaluate potential hires at Basecamp?

I haven't used them, personally, but most sites I've opened with a video background have some sort of delay/pauses because of latency. I can only imagine it would be much worse on some mobile phone. I would create some sort of JS animation or lightweight gif if you want to add more action to your site.
