I thought I'd poke around the "beta" site a bit.
It does have a bit of a harsher look to it. But I do kind of like the black and white and high contrast.
Improved:
- Extended ASCII characters (degree symbol, special quotes, etc) not crashing the editor preview
BUGS:
- Text based emoticons not showing up in the editor. : bike: : bike2: etc
- : foo: emoticon, does it mean anything?
- Manage Attachments from advanced editor, still does not give access to old attachments.
- No uploading of GIFS
