I managed to get RC4 shut off at Square. The only real point of contention
was Windows XP, which doesn't run a version of IE we support, so in the end
it wasn't that much of an issue.

SSL Labs overall statistics paint a pretty dismal picture for the Internet
as a whole, but I think a lot of high profile sites have A or A+ ratings
(i.e. they've disabled RC4) these days which is nice
