On the installer download page (after you click "Get Installer") there is a "change apps" link below the app icons.
That link points to a page like ninite.com/?select=firefox-skype and is a permanent URL, or permalink, to the Ninite frontpage with a set of apps pre-selected. Here Firefox and Skype are already checked.
These pre-selected links are perfect for sharing your app selections on a blog or through Twitter. People can easily see your recommendations while still having a chance to change an app or two.
