I was checking out projects from local San Diego developers and ran across Swurl. One very neat feature that worked so well I barely noticed it: when you reach the end of a page, instead of having to hit “next page”, Swurl automatically loads the contents into the bottom of the current page, so you get the uninterrupted experience  of single long page without the downside of having to wait for a giant page to load. Check it out on founder Ryan Sit’s Swurl page.
