Wondering about that little bar that says, "Tag it:"? It's called a TagBot, and it gives visitors to the site (that's you) the ability to bookmark any article in one of the many Bookmark or Tagging sites such as Digg.com, Furl.net, Spurl.net, Del.icio.us, etc.

To use the TagBot, click on one of the links or icons for the bookmarking sites. If you are not registered at the bookmarking site, the site will ask you to register. After registration, you can bookmark all the articles, on any site that uses the TagBot, to your favorite bookmarking site.

Confused or not a member of a bookmarking site? Don't worry about it. You can still use Wired Antarctica without ever using the TagBot.
