Under the grandiose headline "attention all media" Anonymous just issued a press release (pdf) which attempts to both clarify some popular misconceptions about the make-up of what they are calling not a group but "an Internet gathering", as well as outline the intentions of that gathering.
The whole thing is worth a read. The relatively formal language seems like a deliberate strategy to shift the public image of Anonymous away from mitteleuropan teenagers and make the whole thing seem more credible; if so, it works, insofar as the release sounds like any other association making a reasonable case for what its members are doing and why. The key message is what Operation Payback is intended to achieve:
"The point of Operation: Payback was never to target critical infrastructure of any ofthe companies or organizations affected. Rather than doing that, we focused on their corporatewebsites, which is to say, their online "public face". It is a symbolic action - as blogger andacademic Evgeny Morozov put it, 'a legitimate expression of dissent'."
