Estimate and Access Historical Twitter Data

The application "Sifter" provides search and retrieve access to every undeleted Tweet in the history of Twitter. Powered by Gnip.com, users can submit "Gnip Historical PowerTrack" estimate requests using a variety of query rules. When the query is done, sifter generates an email estimating the approximate number of tweets ("activities") that are responsive to the query and the cost to execute the data retrieval.
