Buzzfeed aims for more viral ads with purchase of Kingfish Labs

Social news site Buzzfeed has acquired Kingfish Labs, a New York startup that processes natural language on Facebook to determine user interests. Buzzfeed said it plans to apply Kingfish’s technology to optimize ad targeting for its brand clients on social networks.

Today in Social

For all the Facebook IPO fallout, companies with “social” in their slide deck can still get attention or raise money. The Canadian reader/writer community Wattpad announced it has raised a $17.3 million round from a group of investors including Khosla Ventures, Union Square Ventures and Yahoo co-founder Jerry Yang. It aims to be the Yahoo of fan fiction. I dunno, but other than jokes, is there a demonstrable market for short-form, mostly user-generated fiction? Meanwhile, RebelMouse, the until-now secretive startup from HuffPo’s former CTO is showing hints of its invitation-only social publishing platform. It has elements of Tumblr and About.me, so users can post and aggregate their Twitter and Facebook content, and a business model that supports premium hosting and, potentially, e-commerce. Finally, I agree with Ryan Kim that Airtime seems to be missing a killer hook. A lack of nudity scanning isn’t what kept Chatroulette from reaching critical mass.
