Basic rule of being nice online--if you want to force your styling and your preferences onto my reading page, then you might think it's cool, but I find it obnoxious and worthy of unsubscribing.

This is especially true of only partially defined changes--people changing the font colour to a dark blue works fine on their light background, but is unreadable on my necessarily dark background, etc

Auto formatting with CSS is a very nifty trick that I like lots. Hmm, wonder if it could be hacked into a layer anyway.
