Background
Happn.in began in early 2009 in response to the rapid growth of Twitter. We saw that Twitter was becoming a valuable source of information, but the interesting content was getting buried. We started Happn.in to pull some of this useful information out of the noise, specifically, the answer to the question 'What's going on near me?' Happn.in was built with the long-term idea that localized communities can benefit from Twitter if they can find and talk to each other.
