I just read an interesting article on PlentyOfFish, the hugely successful one-man-band (Markus, below) online dating site which has some references to the page impressions served by Facebook…

“Markus told me that per page view, Plentyoffish has 5-10 times the click through rate of Facebook. So by his calculations, POF’s 1.2 Billion page views per month is the same as 5-10 Billion Facebook page views per month. Facebook “only” generates 40 billion page views a month and yet it has a $15 Billion valuation”

And while I’m on the subject of Facebook, you should be aware that they are launching a new ad network on 6th November in place of their current Facebook Flyers.
