Alex Tapanaris is the name of an Anonymous hacker who is neither anonymous nor, apparently, a hacker - on account of he accidentally left his name in the metadata of a press release related to the whole Wikileaks infowar.
Rumor has it that Tapanaris has been arrested and his site shut down. Which means we may have our very first real casualty in this whole Internet vs. enemies of Assange pissing contest. Exciting stuff! (Via.)
