Just when you didn't think there were enough random little shops popping up and writing long boring articles.
Social Networking Agency will be quite interesting - it's an area where there is extremely little control available. How do you work with them?
Thee are almost 160 million pages on Myspace - they're going to have to develop tools to track what people are talking about. You can't just rely on Technorati.
Running between Myspace, Bebo, Piczo, Facebook, Friendster and all the other ones will be a difficult job. Good luck to them!
