Whether you use it from your computer's browser or through the iOS app (an Android app is in development), Squrl gives you a starting point for discovering video on several services. Simply click on a site and you can start looking for stuff to watch immediately or save for later.
If you're in a Web browser, clicking on these provider links will take you to the site. When using the app, though, you can browse from within it, making it a more seamless experience.Your account can be linked to sync your favorite YouTube clips as well as your Netfilx Watch Instantly queue. Facebook and Twitter accounts can be linked, too, for sharing videos through those services.
You can build your own galleries and collections, too, but the site and app don't explain anything, so you're pretty much left on your own to figure everything out.
