There are also some comments page styles that get w3m confused in such a way that it renders the relevant bits in more than 80 columns and I have to scroll left and right all the time to read it. I don't know whether it's a w3m bug or not (probably), but it's VERY ANNOYING nevertheless.

The default comments style doesn't do this, so if I had the choice I'd just stick to that for everyone, since in w3m I don't see most of the cutesy formatting anyway.
