Stumbleupon have just launched their URL Shortener - Su.pr - into private beta.

I was lucky enough to pick up one of the invitation codes from Techcrunch - if you're quick, there may be one or two left.

First impressions are very favourable. The interface is nice and clean and offers a wealth of stats about the URL's you've shortened and submitted through Twitter.

You can integrate your Twitter account into your profile and tweet right from the site with automatic URL shortening.

When a user clicks on the shortened URL, they will see the destination URL wrapped inside the "Su.pr Bar", with a lot of the functionality you'd normally find in something like the Firefox extension. If you've come here via the Twitter link, you'll see what I mean :)

I've always liked Stumbleupon and this looks like a very useful tool from them. The stats are very useful but, perhaps more importantly, the possibility of bringing in some extra traffic via Stumbleupon is sure to be a winner.
