Live PageRank is DEAD.

Q: "Is the RK parameter turned off, or should we expect to see it again?"

A: I wouldn't expect to see the RK parameter have a non-zero value again.

Q: What's an RK parameter?

A: It's a parameter that you could see in a Google toolbar query. Some people outside of Google had speculated that it was live PageRank, that PageRank differed between Bigdaddy and the older infrastructure, etc.

I heard rumor that google may be going to a live page rank soon. Is this true?

I highly doubt you will ever see a "live" pagerank again from Google (at least not in the foreseeable future.
