Feedback on Snap Preview Anywhere?

So its been a couple of weeks since I installed Snap's Preview Anywhere that lets surfers get an idea of what's behind a link.

I've read some pretty scathing commentary on the non-utility of the service and wonder what my readers think about the "feature".

Is it just useless "bling" as others have said or do you find it to be a useful addition to the site?

[Update: The bling has been removed. I liked the idea but the practical reality is that it just wasn't all that useful, slowed down load times and had to go.]
