I'm taking a look at the escort section of Backpage and comparing it to the casual encounters section of Craigslist. There seems to be a night and day difference, tons of hot girls on Backpage, lots of fat / mediocre girls on Craigslist.

Example:

http://lasvegas.craigslist.org/searc...ic=1&query=w4m

Any ideas why that is?
