Accelerator in Internet Explorer 8

The latest version of Internet Explorer has a new add-on for LiveJournal users. Accelerator makes it easy for you to quickly post an entry about an article or web page to your journal without having to leave the site where you found the item you're writing about. Just select the text you want to post and let Accelerator do the rest.

Shamelessly stolen from an LJ Letter that everybody got anyway...
