Trendrr - compare and share social data

There are plenty of comparison tools for site traffic. Given a few minutes, we're willing to bet our readers could create a graph of a site's popularity over time. But what about graphing an artist's plays on MySpace or YouTube, how often people write blog posts about each presidential candidate, or how many people are seeding a file on BitTorrent? Trendrr lets you graph, compare, and mash up this kind of data with ease.

Trendrr makes graphing simple by including a drag-and-drop scratchpad that lets you edit and compare graphs with a minumum of effort. The system is based on the RESTful api, which means advanced users can hack together their own trends - there's an example on the site of graphing your computer's CPU usage over time. For everyone else, though, the list of built-in data sources includes popular sites like eBay and YouTube. Don't miss the gallery of popular graphs, which are sometimes informative and sometimes just funny.
