I actually like and support this feature for the reasons
adrianh made in
his node. I don't really see the problem with keeping it as
Petruchio pointed out:
"It's not likely that the site CSS will ever do anything with it..." because the actual class name is our own personal home node id.
One other thing of note is that for individuals like me who don't actually have or make use of a sig, the div tags appear anyway... Not a problem really as a Ctrl-A / delete fixes that in a jiffy.
Just my tuppence worth to come out in support of this feature.
