Let he who casts aspersions actually check to make sure he doesn't make a fool of himself.
The Panic guys definitely did work to make the site work in different browsers. There's some notes up on their blog at http://www.panic.com/blog/2012/05/notes-from-the-bleeding-br.... Of interest is the fact that they spent a day trying to figure out why Firefox was broken, but stopped when they discovered that Firefox 13 Beta 1 fixes it. They also put in workarounds for Chrome/Firefox bugs.
In any case, even if they hadn't done that, there's a far cry between "Designed for IE on Windows", and using new web standards that aren't fully implemented in all browsers yet.
