What has Facebook done that can be described as 'innovative' since the wall? Their only 2 decent products since then have been Connect and Like, neither of which were innovative (though they were good enough implementations to reach ubiquity). And they've released many products that are just down-right poor; Places is me-too and no one uses it, Messaging is just a mess, Groups is buried and unuseable... Facebook is riding off the network effect. It makes me wonder what exactly is going on there, as they have some of the best engineers in the world; why are they not putting out stellar product after stellar product? They've taken care of scaling already; what are these geniuses doing?
