Time Magazine currently has a special feature on the 10 Ideas that are Changing the World. If you want to know what Synthetic Authenticity and Reverse Radicalism are, then this is the place for you: interesting stuff.
At a more micro level, Social Innovation Camp (which unfortunately I'll miss, despite working in the office below) has announced its shortlist of 6 ideas to be given a thorough going over in a couple of weekends' time. So if you want to know what Barcode Wikipedia and Stuffshare might be, go check it out; (could be) interesting stuff.
