Snap Previews- Flashy vs. Functional?

You may have noticed a new feature that we've implemented on a very limited basis. The free service is called "Snap Previews" and it allows you to create dynamic links with a pop-up preview of the link. Seting up the feature on your website is a snap (no pun intended), only requiring the addition of a few lines of code.

As designers, we're torn whether this feature is a good idea. On one hand, it's kind of flashy and cool. On the other hand, the large preview window can be a distraction, clunky to use and not very functional. If you're a designer, you understand striving for a balance between functional and cool.

We first displayed Snap Previews earlier this month and have used it very sparingly ever since. In retrospect, this must mean that we've subconciously concluded that the "coolness" factor didn't outweigh the loss in functionality. Either that... or we've been too lazy to add the extra line of code. :)

The flashy vs. functional debate of "Snap Preview" has me torn. To add to my confusion, I continue to see other popular blogs heavily using Snap Preview on nearly all links. So, the question must be asked... is this feature just flashy or is it really functional?
