I read the IPv4 address space thread and thought this might be of interest to the group:
Some months ago I setup a small test to test if users browsing http://www.pool.ntp.org/ supported IPv6:
It's slowly been creeping up to 2.8% this month (from ~2.2% in November). At this rate we'll have critical mass (say 25%?) already in 2022!
Kidding aside, although most of the test data is from NTP Pool website currently I've been testing a few different sites and the numbers are all pretty close.
The code for the system is at
http://git.develooper.com/?p=v6test.git;a=summary and http://github.com/abh/v6test
I've also been testing how many fails to handle A+AAAA records and it seems to be about 2-3% -- which sounds like more than plenty for Google, Amazon etc not to enable IPv6 on their regular hostnames where it matters.
 The number on the "global" statistics page is artificially low because many of the tests have been via a host with both A and AAAA records and I forgot to take that into account when calculating the numbers. Oops. I'll get it fixed.
