I'm also surprised of the price, it seems low compared to many tech acquisitions. TechCrunch has a lot of eyeballs, even if it doesn't have main stream audience.
Midsize Finnish regional newspaper companies have market caps around €180M. TechCrunch, a major international tech publication with millions of readers, is worth of only 10-25% of a local newspaper with audience of 300000 people? WTF? Either newspaper valuations are absurd, or internet advertising and tech events are a failure as a business model.
