Kind of a pun, for this blog, but I added Snap Shots

I added a tool on this site called Snap Shots that enhances links with visual previews of the destination site, interactive excerpts of Wikipedia articles, IMDb profiles and Amazon products, display inline videos, RSS, MP3s, photos, stock charts and more. Sometimes Snap Shots bring you the information you need, without your having to leave the site, while other times it lets you "look ahead," before deciding if you want to follow a link or not.

You can disable Snap Shots by just clicking the Options icon in the upper right corner of the Snap Shot and opt-out.
