Scott came back from SXSW all jazzed about microformats …and really, who could blame him? It’s something so simple and easy to implement (it’s just markup) that to not embrace them is an act of stubborness.
But the first step in taking advantage of a microfomat is knowing of it’s existence. For that, we have Tails, a nifty Firefox extension that alerts you to the presence of a microformat. You do use Firefox, don’t you?
