I just installed a nifty little tool on this site called Snap Shots. I'm not sure if it's going to be helpful or annoying, and I would really appreciate your feedback. I'm not sure if it will clash with the amazon text links, and this is just an experiment - so please put your two cents in.
To activate it, hover your mouse over that little icon next to all the active links. A snapshot will pop up with visual previews of the destination site, interactive excerpts of Wikipedia articles, MySpace profiles, IMDb profiles and Amazon products, display inline videos, RSS, MP3s, photos, stock charts and more.
The benefits to Snap Shots is that it's supposed 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.
To disable it, you can click the Options icon in the upper right corner of the Snap Shot and opt-out.
If it is universally disliked, I'll pull it out. If it seems useful for the external links, I'll see if I can modify it so that it ignores the internal links and attaches only to the external ones. And if you guys like it how it is... we'll keep it.
