Truemors, a rumor site launched by Guy Kawasaki in May 2007, has been acquired. The buyer is NowPublic, a “participatory news site” that we covered last year when they raised their second round of financing. Kawasaki is joining the company’s advisory board as well.

The terms of the deal aren’t being disclosed, but my guess is that it’s very likely to be a tiny acquisition. Truemors remains a niche within a niche, with flatish traffic.

Now if Kawasaki can sell his other experimental startup, AllTop, I’ll be impressed. Its so awful its kind of cool.
