TechCrunch head Michael Arrington is so attentive to detail. He posted a Twitter last night asking about a Google page's redesign. "hmm, how long has the google advanced search page looked like this? http://tinyurl.com/6rb" Moments before, however, Arrington posted a now-deleted Twitter with the same question but a different URL: http://tinyurl.com/3776ez. This URL links to a Google search page, but with "site:duncanriley.com arrington asshole" filled in as the search term. Duncan Riley is a contributor to TechCrunch. A little dissension in the ranks, Michael?
