This week on the GeekWire radio show and podcast, we explore Paul Allen’s new space venture, assess Google Chrome’s rise vs. Internet Explorer and Firefox, and offer a second take on Twitter’s recent overhaul, now that we’ve been using it for a week.

We’re joined in the studio by tech blogger Andru Edwards of GearLive (and the new Ask Andru column!) who gives us a rundown of his top picks for last-minute tech gifts.

Our App of the Week is an personal organizer for holiday shopping, and our Name that Tech Tune challenge brings back a classic holiday memory from another galaxy.
