I'm the opposite; I would have preferred less info on the Overseer and wasn't too fond of the "he's watching you" stinger. All in all, though, I thought this article is great. It uses the idea of mass surveillance to instill a great sense of paranoia despite the relatively slim danger of the anomaly (as long as you keep your shoes on near cameras, anyhow).
Telling how an SCP is going to murder you gruesomely isn't very creepy. This article doesn't tell you what this will do to you, when it will do it and most of all why it will do it. The fact that this is told using a perverted idea of the law (where the law is seemingly arbitrary but no less inflexible) makes it even more effective.
Also, don't tell me the -Bs don't have a little bit of Judge Dredd in them.
