Arrington’s TechCrunch looks for VC

My colleague Alex Haislip, who is traveling on assignment, heard from a reliable source that Michael Arrington, head of super-popular blog TechCrunch, has been talking to at least one “well known” venture fund about raising some capital. The source also says that the VC isn’t Sequoia Capital or Kleiner Perkins. 

Anyone know who it is? We put in a couple of emails and a phone call to Arrington but haven’t heard back.
