Happn.in
Posted: June 6th, 2009 | Author: CJ | Filed under: Technology | 1 Comment »Happn.in is a new service design to show you what people are twittering about in your city. In addition to all the various city-specific Happn.in twitter streams, you can also follow the site itself: @happn_in. I looked up Sacramento to see what people were twittering about.
