And Tim Heuer has a couple of cool accelerators to share:

I first saw the accelerators (the artists formerly known as activities) during The Code Trip, when Woody created an IE8 activity for Wikipedia.  It was a convenient tool to have in your right-click toolbox on IE and I loved it (and still do).

Well, now that IE8 Beta 2 is out, I decided (well, my selfishness decided) that I should create an activity accelerator for something that I use often so I introduce you to: IE8 Accelerator for TinyURL.  So with a little XML, it was done.  Seriously, like < 5 minutes.  I ran into one problem with URL encoding, but Kevin at TinyURL fixed his end to handle the encoded URL information sent to his service.
