Anyone who thinks blogs can't make money should check out Gawker. This growing stable of blogs just added Lifehacker, a slick tech site sponsored by Sony. Dan Gillmor reports that Sony will pay in the range of $25,000 a month to sponsor the new site. The deal also includes some ads on Gawker's other tech site, Gizmodo. The question, of course, is whether these are really blogs or simply commercial web pages. Fact is, the line between the two is fast blurring.
