It's like digital crack. You get a sensational story, and it's kind of cool because it makes the startup world seem more attractive and now you have this overconfidence that you can do it, because well it's just easy and it looks like fun. It's probably better to read the full stories and get the full context. The founders aren't usually in the media to talk about themselves anyway; they're out there promoting their startup, so you're mostly walking away with a sales pitch (although startups do this to varying degrees, Indinero comes to mind when I think of startups who are most intent on using media coverage to grow, just an example). This video was definitely cool though, it's fun to see how they all work. They have one of the best pitches for hiring: "we have some of the smartest engineers" is an easy sell.
Check out the book if you want all the back-stories. It's pretty sobering; a nice break from the koolaid, so to speak.
