Damn, I went to dig up the URL for reddit's source and it seems it is no longer open :-(
Chris Slowe is the hand guiding the ship day to day, with a bunch of really passionate hackers underneath him. They are maintaining like 4 different code bases and keeping feature parity as best they can with a team that could still comfortably go on a ski trip together (compare that to the 60k+ at Facebook). The users hate change while also demanding new features. The business makes no sense. Steve is off doing... something, to ads or something and make investors happy so they keep the ship afloat. UI is going to hell to drive DAU metrics for investors. Banning shitweasels brings down the wrath of the conservatives. Yet they are still working their assess off to keep a mound of spaghetti from bursting into flames with 1/10th the staff they need to do so.
