Leo Laporte of This Week in Tech hosts a This Week in Google on G+ with Google VP Bradley Horowitz, Vic Gundotra, Matt Cutts and other Googlers explaining the inside of the Google Plus development and decisions.

A great show that needs no comments (from me). But I can’t hold back saying that there are some very insightful remarks on video conferencing from Vic Gundotra and Bradley Horowitz. And they reveal that Sparks is just a placeholder from which other services will be added.
