Technorati, still trying to figure out what it is, is now an online ad network: it has bought a small LA-based online ad network AdEngage. Terms of the deal were not disclosed. AdEngage was founded in 2004, and according to the company, serves about 12 billion ads on 4,000 sites each year, most of them smaller sites than Technorati’s own new-ish ad network. The company has also launched a private alpha of “Technorati Engage”, a self-service ad network for blogs and social media sites, based on the latest acquisition. More details here.
