While the two sets are among those available for no charge, Infochimps sells the more in-depth and extensive datasets it’s derived from Twitter, proving there’s a continued marketplace for this sort of information. For $300 you can buy the dataset containing an hour-by-hour breakdown of the occurence of hashtags, URLs, and smileys in the 1.6 billion tweets created between March 2006 and March 2010. For $250 you can purchase a dataset extracted from those same 1.6 billion tweets with all mentions of stock tokens and related keywords.While information from Twitter has been culled to assess which websites we’ll like and which movies will perform well, analysis from Twitter and from the expanding social graph is really just beginning. Like, for example, the ability to track the time and mention of stock names.
