I don't know from AJAX badges

I don't beat myself up anymore for not keeping up with everything happening on the internet. You just can't.

AJAX is something I don't know about, don't quite get, but it's creeping up on my not-written-down brain nag list.

This badge thing seems kind of cool. Rod Boothby describes them as "a way for non-technical users to drop AJAX-powered interactive tools into their blogs and wiki posts."
