Clearspring’s mission is naturally to serve as large an audience as possible, and the acquisition of AddThis certainly helps to expand the purview of its newfound parent and proprietor. AddThis is a bookmarking and sharing utility that has been adopted by a range of third parties, including media outlets such as Time, Fox, ABC, and CBS. MySpace is also listed as a client, making its reach quite notable indeed.
Of course, in buying AddThis, Clearspring itself now faces the competition of ShareThis, a service with a similarly broad base of use. And, as Kara Swisher of BoomTown notes, the fact that neither Clearspring, with a claimed $10 million in annual sales, nor AddThis, with “negligible revenue,” together make a profitable collection of services, it’s not yet certain where where their businesses stand.
