Some aggregate stats since launch (Mar 21).

I looked over a period from Mar 21 - Apr 5 vs. Mar 5 - Mar 20. There was 
a marked shift in the data starting Mar 28, which is when it looks like 
the first big reindexing took place.

Here are the changes in page views for each doc version:

current: + 184.05%
14:      +   7.84%
13:      -  12.46%
12:      -   4.92%
11:      -   0.46%
10:      -  11.38%
9.6:     -   2.60%
9.5:     -  30.32%
9.4:     -  15.02%
9.3:     -  22.93%
9.2:     -  21.60%
9.1:     -  33.10%
9.0:     -  27.80%
8.4:     -  10.24%

So it appears that there is a traffic shift to the most recent docs 
based on the rel=canonical change.

The next analysis will be to see how much people are clicking into an 
older version of the docs after they land on a particular page, and if 
so what versions.

Thanks,
