Why does Brian McCullough say “Nothing for you today, talk to you tomorrow” at the end of the podcast Techmeme ride home?

I’m a fairly recent listener of the Techmeme Ride Home podcast and I always wondered why some times the episodes would end with “Nothing for you today, talk to you tomorrow” and today’s episode finally explained it.

I often have something to say outside the regular confines of the regular show, and when I don’t I say “Nothing for you today, talk to you tomorrow”
