i've been covering Facebook as a major wheelhouse for years, and I've noticed at least a dozen I could name if pressed. That means there's probably a lot more I haven't thought of.
Valleywag isn't exactly the best hard news source, but when it comes to corporate culture type stuff, which is what i'm referring to, they're generally not bad, particularly in their hey-day when Boutin, Owen and the rest of the gang were still there.
