As much as I love bashing Microsoft, the CSS1 recommendation ties these pseudo-classes directly to the anchor tag.
I guess that this is what I meant. I occasionally used psuedo-class for links (I feel, as they were intended??), ever mindful of the possible horrid color-on-color possibilities and while I do like the visual stylings of tabular text that, on-hover, highlight specific rows and/or cells, to me, this does very little except tease me. Eye candy. While I do like it, -I just don't use it myself.
I have very little use for psudeo-class beyond anchors. I've done a few sites that have a fairly notable handicapped viewership, and formerly being 'legally blind' in one eye myself, am always noteful of and strive to include at least a few of the corrective issues pertaining to web accessibility for the handicapped. But for the magic of laser surgey four years ago, I'd still have somethng like 20/90 vision (or worse by now?) in one eye (barely correctable by wearing glasses then and virtually no night-vision whatsoever. Now, 20/25 in that eye and have 'average night-vision'. I can drive a car day/night and without glasses!).
I did bookmark that URL provided though. Very nice effect and I could see myself using that somewhere in the future for the very same effect on some tabular data.
