Snap Preview Anywhere Plugin is an interesting plugin and it seems to be really helpful.

Before you’ll access a link, you’ll have a snap preview of the web site you’re about to visit, making your surfing much easier.

All you need is to download and install the plugin and then get a SpaKey.

Snap Preview can also be used on non-blog web site as well with a html code.

For more information, visit Snap.com and Ajay’s blog.

Extra:

To preview links before you visit them, you can also use Cooliris Firefox extension.
