According to a recent report, 97 of the top 100 classified sites are just localized versions of Craigslist
, up from 88 just last year. Combine that with a massive rise in traffic to classified sites in general and you have a recipe for one raging behemoth. "Craigslist isn't just crushing the newspaper industry and crowding out other classified sites. It's also taking an increasing slice of total U.S Internet traffic: the site's market share in February was up 90% year over year, accounting for about 2.5% of total US Web site visits."
