Most "interesting" new features are their answer to the "Widget" paradigm - called "Webslices". IE8 can discover self contained "webslices" inside webpages and add them to the browser as widgets.
The other interesting new feature is a product called "Activities", which appear to be an integrated "mash-up" tool, used to do integrate with lookup- or sharing-type services. Idea being that third-parties like Facebook, Google or whomever, could supply these services on their websites, and the IE8 user can choose to plug in this "Activity" and then be able to use it as an integrated part of the IE8 browser.
Oh my ... it's a revolution of the entire internet! :-/
"Nothing to see here - move along"! Only issue is the bad choice of name for the "Activities" product, which have very little to do with an activity in my book. But thanks for fogging up the term, guys! ;-)
