Matt Cutts Grab Bag

Good Q and A session over at Matt’s blog.

Couple things I didn’t like:
The very generic answer about RK. Specially if RK does represent some sort of internal PR calculation.
Rolling out Big Daddy to all the datacenters without fully addressing the supplemental issues first. Why not wait on rolling out Big Daddy across the datacenters until the issues were all fixed/tested.
No answers discussing the 301s.

My favorite comment:

>You could whitelist the IP range that Googlebot comes from in the mean time.
Do you have a listing of all the Googlebot IP addresses?
Thanks.
