Steam website broken?

Happens from time to time.

same here. OMG WE"RE BEING HACKED.

Yeah, steam update fail.

Yup. I've seen this occasionally before, but usually only briefly and only on part of an app.
It's the variables Steam uses for their website strings, i.e. text.

Something must be barring the Steam website from being able to translate those string IDs into the correct text, as they normally would. Odd.

Nope
