Serious question. Why doesnt Facebook do any engineering talks anymore? Some of the coolest talks on infrstructure from the past few years have been from FB. And yet the only thing i can remember really hearing about their stack recently is that they were using HBase. Which really came off as more about marketing and hype about some products they were working on then truly geeky stuff thats come out from FB in the past. Anybody know? I wonder if its because Fb is no longer a startup? Which might the reason why we never hear about Youtube or Twitter anymore either. Oh my other comment was just meant in jest. But thanks for downvoting it and killing all the worthless and meaningless HN karma points i had accrued!
