Now that you mention a comment class: perhaps it would be a good precaution to protect comments from mutilating each other, now that people can use arbitrary HTML in them. I noticed that when I try to put an image in a comment with float:left style, it will protrude from the bottom (if the image is tall and there is little text), messing up the comment below it. I learned to prevent that now by putting the entire comment in a dummy 1x1 table; then the image just floats to the left of the table cell, and the cell will expand to contain the image, pushing the comment below it down, without messing it up. I don't know if there are more natural ways to confine formatting tricks to the comment that contains it, but it would in general be good if there was some isolation. So perhaps the comments should be formatted as 1x1 tables by default.
