I'm curious about their "480% increase in ad impressions" - I find this a disadvantage than a feature. It may increase their impressions, but will lower their CPM and CPC rates in the long run. Furthermore, its a hassle to the user since it steers them away from the content.
The blog focus is unfortunate. There's only a small subset of bloggers who make any kind of money to speak of, and then there is an even smaller set who will be regular customers.
I notice that they have a Drupal plugin, Twitter functionality, and code to embed the gallery in your webpage. Why then the focus on blogging? It's not just limited to the Tech Cruch article, it's self described: "Launched in early 2009, Picturesurf makes tools for pro-bloggers."[1].
Seems like a case of premature branding. No need to make your target audience so small initially.
Does anyone see differently?
