I have just read a very interesting post on the Google vs Viacom lawsuit on Mashable.com (a leading social networking blog).
(N.B. If you are new to the topic check the previous post on this blog for background info).
The Mashable article is very condemning of Viacom in making their requests for logging history, and also critical of the US judge who ruled in their favour on the action, mainly out of anger that Youtube users might now be at risk from facing potential (and probably successful) copyright violation lawsuits from Viacom.
