All three of us. :p
I downloaded the Windows Phone 8.1 Developer preview today. It includes IE 11 mobile, and appears to mostly work with nuKinja now!
The cursor moves with the typing, and the autocorrect appears to mostly be accurate. It makes commenting way better than commenting with IE 10 Mobile.
One problem that I have still is when I comment the first character is typed, then magically it indents and hits enter for the second one. It isn't hard to workaround though.
So hang on everyone! There is bug-free commenting in your future if you use windows phone! (typed from my phone)
