Reading the latest in the spat between Wired's Epicenter blog and Michael Arrington over the Washington Post's deal to syndicate TechCrunch articles and the ethical propriety of the TechCrunch editor's investments in startups his blog covers, I noticed that the post was in the category "ButtMunch." The latest post states that "We have nothing against Arrington," but the tag originated last week in a post that accused TechCrunch of pilfering a story angle related to Steve Ballmer's continued tenure at Microsoft in the wake of the Yahoo deal.
