Michael Arrington drinks Valleywag's milkshake at TechCrunch meetupSJason Calacanis, the Mahalo CEO and email list administrator, and Michael Arrington, editor of TechCrunch and hero to hopeless website creators, held a meetup in Menlo Park last night for finalists in their TechCrunch50 startup beauty contest at the British Bankers Club. Our spy infiltrated the proceedings — and served Arrington a milkshake. "He didn't seem too happy about it," reports our informant. More photos from the event — including a surprise appearance from CNET TV star and former TechCrunch writer Natali Del Conte, who came after the proceedings were over for a brief tête-à-tête with Arrington.The crowd was small, our spy reports — "about 20-30 people, mostly TechCrunch50 finalists." SearchMe.com was one of the finalists — "some woman even Twittered that they got in." Arrington drives a gray Porsche, and "left with a ladyfriend, didn't get to see who." (Anyone know who he's dating? Do tell!) On to the pictures!
