I'm looking for someone to develop a method to gauge the highest trending topics, names, product names etc from the social world. Taking feeds from Twitter, Facebook, Google Buzz, Gowalla, Foursquare and more, I'd like to have a continually updating database of those items which are trending, and maintain a database of the keywords, hashtags, trends etc. The database would flush after a certain duration, to keep the data fresh, and data volume, manageable. I'm entirely open to ideas on this, and the language/platform required. I do NOT want a website, I just want the connectivity, filtering and storage.
