Lets not get rude, I've met some of them. They're bright folks using all sorts of technologies. I've seen vim and emacs (though mostly emacs). Their website does have some rough corners but they're working on a 10+ year old codebase and you'll get that as technologies age out. Their product however isn't just their website but instead their service. (The're a social company that isn't about virtual networks but physical ones.) And judging by how they fixed the misunderstanding it's doing pretty good.
