The WSJ article was about NSA requesting CDRs from Verizon. This is not the same as having unrestricted access to private user data as the presentation titled PRISM claims.

The strange thing is that just having a presentation is usually not enough for the HN crowd. If it would have been, I would never have to execute on any of my ideas beyond the presentation stage. Personally, I really don't think some making a presentation is really evidence of anything.

I'm really not sure why HNers reacted differently in this instance though.
