Two small — but noteworthy — acquisitions for Thing Labs, the company behind Facebook and Twitter web client Brizzly: Thing Labs has purchased Wikirank, a tool that let users visualize and compare the most popular topics on Wikipedia, and is also announcing the purchase of Twitter iPhone client Birdfeed.
Thing Labs has added some of its own features to Birdfeed — and is using it to launch a Brizzly app for the iPhone. Wikirank, meanwhile, will be integrated into Thing Labs’ Brizzly Guide, “a new site designed to help navigate what people are talking about on Twitter, Facebook, and other social spaces.” Hot topics — like ‘SXSW’ — have their own pages, which feature an explanation of why they are popular, along with some relevant links.
Terms of the acquisitions were not released. Thing Labs was started by Jason Shellen, a former manager of new business development at Google (NSDQ: GOOG), and Chris Wetherell, who — while at Google — started Google Reader. The startup has raised funding from Mike Hirshland of Polaris Venture Partners, Jeff Clavier of SoftTech VC and Michael Jones.
