We recently launched a new website that provides a URL shortening service for “multiple” websites: http://www.viewista.com Viewista creates a short URL for “multiple” websites. Plus, you can view the multiple sites all at once. We think it can be a real time-saver. You can also post comments on the sites and share with your friends, making it a social URL sharing service. Viewista can be particularly useful on Twitter because a user can create a short URL for multiple sites on a topic without having to use multiple tweets.

Also regarding why they suck…. John Gruber linked to David Weiss on the Security Implications of URL Shortening Services.

What?! No one uses Freaking Huge URL Generator?!
