Ariel Waldman is totes singleOur apologies to Ms. Ariel Waldman — she is not dating Cal Henderson: "I need dates — stop ruining my game, yo," she Twitters. Good, because that would make for some awkward meetings at Pownce, where she spends time as a community manager working with cofounder Leah Culver, a former Henderson paramour. This also means that polytalented Flickr code jock Cal Henderson is probably available. Probably. "How did Valleywag miss the girl I was actually there with?" he later asked us.
