Yes. I agree. It's quite useful to mask that. In the event of the user
not having Torbutton enabled - Am I right to assume that they would
probably leak their language choice? I think it will but I'm an English
speaker and I haven't tested it.

How do you feel about using https for this? Phobos bought us a cert that
should be good for the rest of the year. Ideally, if we use SSL, we're
going to have even less of an issue leaking possible linkable language
information to exit nodes.
We probably also want to ensure that any link on check.tpo doesn't leak
a referring url that includes their language choice.

It does seem like a reasonable thing to do at some point. I certainly
have wanted to integrate the language with the "it doesn't appear that
you are using Tor" message. It's not very helpful to have that in a
language someone doesn't understand.

Right. I think this underscores the need for trust in running

I think this is good providing a switch to https://check.torproject.org
