The Localization of Social Media

A few weeks ago, my colleague and I gave a presentation with our predictions for social media in 2010 (you can see the presentation here).  One of our predictions: increased localization of social media.  Well, this is already happening.  Last week, Twitter announced lists and within several hours there were a handful of "Arkansas" lists.  Now, Twitter has announced that they will soon launch trending topics by city, state and country.  With the new API, users will be able to learn what is happening specifically where they are located.  Very cool.
