Good question.

Atrios asks...

Exactly why is anything Newt Gingrich says newsworthy?

Good question. So good, in fact, that it should be put, pointedly and repeatedly, to anyone and everyone who cites, quotes or interviews the disgraced former Speaker on any subject in any venue.

An exception can be made, I suppose, should he be heard to say "Guilty, your Honor," in a superior court somewhere.
