This Lifehacker comment thread made me go researching on what I might use for Webclips, but save for the front page of my favorite blog (TUAW, duh), I couldn't think of anything I'd really want to keep on my Dashboard 24/7. I did like the idea of putting Woot.com (and Shirt.woot, which I've been looking at a lot lately) on there, but as a few of the commenters say, webclipping (can I verb that?) the entire page makes things a little too big.
Fortunately, David Elliot piped up about the Woot.com widget, which easily and quickly lets you monitor the Woot sites from your dashboard, with a minimum of space taken up. And now I've got two instances of it running on my Dashboard, one for regular Woot and one for the Shirt version. I especially like that it includes Growl notification, too -- if I happen to be working around midnight and a really good deal pops up, I won't miss it.
Of course, you may not want to have something popping up on your Dashboard all the time tempting you to spend money. But if you're already following the Woot empire (and to tell the truth, I almost never buy anything-- I just like looking), the widget is an easy and simple way to stay up to date.
