I never saw the spam angle; probably because I'm a regular StarShipSofa listener and Larry is well known there.
But I do notice that SSS promotes Escape Pod on a regular basis, and this is rarely reciprocated. So it's good to see them getting a plug in the forums, at least.
Now I think of it, Larry would make a great Pseudopod narrator. He could narrate Thomas the Tank Engine and make it sound scary.
