Snap is this little thingy where, as you mouse over a link, you get a preview of the link’s website. I’m going to try and see if I like it. Guy Kawasaki uses it on his blog, so I’m sure it’s reputable.
Let me know what you think. You can turn it off if it irritates you or configure it — just click the OPTIONS tag in the upper right corner of the Snap window. I think it’s kinda’ cool. I installed it and tried it with the icons, but found that intrusive so I removed that.
