That's not a pageview, that's a view. If you're on POZ, the actual website (not Tumblr), that doesn't count as multiple pageviews. We do Read Mores predominately for aesthetic purposes (not having ugly tweets, text, images, etc) in the general homepage of the site. We also do them to draw people away from the Tumblr Dashboard onto the main site. And yes, some of that is obviously for views. Views though, not pageviews. I frankly don't care about pageviews. Ads aren't of interest to me - Pageviews are a shitty way to generate money, even if it's the accepted formula.
That was long, sorry.
