Snap Preview Anywhere enables anyone visiting your site to get a glimpse of what other sites you’re linking to, without having to leave your site. By rolling over any link, the user gets a visual preview of the site without having to go there, thus eliminating wasted “trips” to linked sites.

Here’s a quick note for the webmasters. If you run a blog, site, whatever, I highly recommend you sign up for the free (as in beer) “Snap Preview Anywhere” service at Snap.com. With just a little bit of JavaScript in the header and footer of your page(s), you can give your visitors a preview of links which lead off-site, while suppressing the feature for local links. It’s relatively fast in generating previews, and the JS does not break the DOM. Nice. Did I mention it’s free?
