CNET Networks (CNET) is acquiring FindArticles.com from LookSmart (LOOK) for $20.5 million. That's less than half of what they just sold WebShots, their photo-sharing site, for. FindArticles.com has a database of 11 million articles going back to 1998 from newspapers, magazines, journals and similar publications. The difference between WebShots and FindArticles is that it is easy to offer advertising with FindArticles, even if it only Google Adsense. That's very hard to do with WebShots, because the computer can't tell what the photograph content is. So CNet will be able to use FindArticles to more effectively advertise and attract users -- smart move.
