yup :) Except I've been doing it manually as I see comments/commenters that interest me and adding them to a greasemonkey script that decorates posts with icons identifying users and their affiliations. Does that make me evil?
If I find some free time I might download this and run some extracts as sytelus suggested.
I'd bet that you're not the only one who thought of that. And for less money I'd bet that someone has beat you to it.
