The FiveRuns and RailsEnvy guys created videos for the Rails Conference, which just ended. They showed one of the videos before every keynote (you might remember last year’s Mac vs. PC / Rails vs. PHP ads too, which were also hilarious). You might come away thinking these guys are too-cool-for-school, but then again, they just might be on to something.
