Personally I don't use them (bar 1 site that I'm ordered to by those above). Like I said below they make sense for a photo site as a slide show but not much else. BUT EVERYONE MUST HAVE ONE!!!!

for how a modern site MUST LOOK, even though that look seems to have become popular more through lazy development than usability testing.

There's no mention about whether the carousel should be switching slides by itself over time, though. And that's what I find most annoying about those things.
Whenever you actually get tricked to reading something there, the bloody thing rotates before you finish. THAT is the biggest reason I completely ignore them, even the ones crafted as your link suggests.
