I think he's referring to the opening line: "PRISM is a clandestine mass electronic surveillance data mining program"
Electrospaces describes it as follows: "It shows that PRISM is not about bulk or mass surveillance, but for collecting communications of specifically identified targets." [1]
That quote is from one the sites listed on nsa-observer.net's front page with the description "provide[s] documents and in-depth analysis on the NSA." Based on the author's Twitter feed, I'm assuming he's based in the Netherlands.
