Snap Previews

I added Snap Preview Anywhere™ to my blog. I'm not sure I like it but a friend of mine works for them and I thought I'd give it a try. Does anyone find it annoying? Tollerable? Cool? I don't really navigate around or read my blog once I post but the few times I have lately it's been a bit jarring. Perhaps just becasue I'm not used to it. We'll see. I'll give it some more time and decide if it should stay or go.
