Vantaggi
There is som interesting technology and clever people to play with it. When i was there there was still plenty of money for regular corpotate budgets so there were fringe benefits. Some people were great to work with.
Svantaggi
Lots of people were still stuck in the startup mentality which was over years ahgo. Also tons of media people who don't realy get technology people, and the media people were very much in charge. That made an enviornment where it made more sense for people to swagger and bluster and claim their area of power instead of workig together to make better things and sharing information. A separate structure grew up insde the normal one where people who liked each other did normal work for each other, but would masively hold back for people outside the network. Which was great when you were part of that network but bad when you werent, and either way projects that diserved to be completed got smashed because of that power dynamic.
