The digital trends for 2011 are irrevocable: Crowdfunding, exchange confidences, music, social networking. Yes, social networking is still alive and already taken to the next level. Especially with Foursquare – a web service that allows you to tell people where you are. I was surprised to see them again in 2011s hot list of web sites to watch. Facebook has launched its Facebook Places service in 2010 and it seemed as if they would kill Foursquare?!
