Facebook's relationship with the public has always been quite interesting. It presents a quandary: Facebook's main (only?) source of revenue comes from advertising, but if they make too much too public too soon, they'll lose their entire user base. So, they've been making changes over the last few years that greatly facilitate advertising, while minimizing the rate of increase of user dissatisfaction. It bothers me enormously that users have complacently allowed Facebook to operate in this way. What's more fascinating is the level of innovation we see from a company that employs over 2,000 people: it's not too incredibly impressive. I'm sure most of their work is in maintaining their 60,000 servers, but even still, for the amount of salaried engineers they have, wouldn't we expect something more impressive than a product that has remained relatively unchanged for the last few years?
