BlogDigger launched in 2003 as a competitor to the then dominant Technorati, and launched a locally focused search facility in 2005. The site offers standard blog search, and unlike Technorati has constantly focused on its core product.
For the new Odeo (formerly SonicMountain) this is their second acquisition in just over 6 months, having acquired FireAnt in September.
According to a post from Greg Gershman on the BlogDigger blog, Blogdigger’s aggregation and search technology has been integrated into Odeo’s new beta site. Gershman has joined the Odeo team as Vice President of Search and Engineering.
