How about this for a manual (non-scalable) translation?
I could not have written it (much ;)) better myself. Also regarding the cheatsheet -> Markdown thing I have been recently reviewing and am currently using the package again somewhat more myself.
I don't think mixed language threads will be very helpful (as you said)
In the example above just got confused with the option of e-mail-answering to a thread...
"Wer den Schaden hat, brauch für den Spott nicht zu sorgen"
(The laugh is always on the loser.)
