TwitterThoughts creates charts based on Twitter tweets in combination with lots of APIs: From a sample of 600 tweets/minute served by the Twitter Api that we send to Yahoo Pipes where it extracts all phrases from the tweet text and the latitude/longitude with use of Yahoo YQL . This Yahoo Pipe outputs serialized PHP back to our local update script that grabs every tweet and phrase and puts it in our MySql database.
