TechCrunch blog founder Michael Arrington will expand his web empire today with an enterprise blog, according to a source. TC writer Nik Cubrilovic (who also heads web startup Omnidrive) will edit the new site.

Why is it important? Because Arrington's web network (The blogs TechCrunch, CrunchGear, MobileCrunch, and TechCrunch UK</>; the TalkCrunch podcast; and the CrunchBoard job board) may pull just 100-150k views a day, but that's an audience of startuppers and wannabe "Web 2.0" know-it-alls. In other words, Arrington is an accidental Moses for a nation of entrepreneurs.

Or Head Lemming. Your call.
