The technology choice was probably outsourced because the "right people" are probably busy as hell. Beyond that, how many people are ACTUALLY going to watch it there, rather than a Flash-supporting streaming site ... say, CNN? Over 1.1M people have signed up on Facebook to watch the stream live via CNN. I don't think anyone gives two shits about the "official" site and what technology it is or isn't using. There's plenty of alternatives. Just about every major news network is streaming the Inauguration online.

They're making a game about the life-cycle of code in source control?
