See the full post for more details on a beyond-the-basics hypertext capability in IE8
There’s a new site called Liveslices.com where those of you running the IE 8 Release Candidate can browse through and install Webslices from an online gallery. Webslices are a new way to keep up with frequently updated webpages using the new version of IE. When you subscribe to a Webslice (look for a green button), the “slice” is added to your Favorites bar sort of elike a bookmark. You can click on the Webslice/bookmark anytime to see a dynamic window appear with relevant info about that web page – all without leaving the page you’re currently browsing.
