I'm not sure what's up with those numbers though -- they're *really*
unrepresentative of what we see for numpy otherwise. E.g. they show
3.X usage as ~5%, but for numpy, 3.x usage has risen past 25%.
(Source: 'vanity numpy', looking at OS X wheels b/c they're
per-version and unpolluted by CI download spam. Unfortunately this
doesn't provide numbers for 2.6 b/c we don't ship 2.6 binaries.) For
all we know all those 2.6 downloads are travis builds testing projects
on 2.6 to make sure they keep working because there are so many 2.6
downloads on pypi :-). Which isn't an argument for dropping 2.6
either, I just wouldn't put much weight on that blog post either

(Supporting 2.6 in numpy hasn't been a big deal so far AFAICR, but I'd
be in favor of dropping it as soon as supporting it becomes even a
minor hassle.)
