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.
