Want to see LinkedIn CEO Dan Nye flinch? Do what Fox Business correspondent Liz Claman did this morning and ask Nye if rival social network startup Facebook has expressed interest in acquiring the company. "It just seems like it would be a perfect for say, a Facebook, to join up, to link up with you guys," Claman advises Nye. Suddenly a happy little conversation on camera turned awkward. Did he flinch because Facebook had expressed interest? Or because, unlike Claman, he knew Facebook wasn't even sniffing around — an admission that would call into question LinkedIn's value right when Nye's gunning to take the company public? That moment, above, and the full interview — replete with Nye's nonanswers about acquisitions and IPOs — below.
