deeplinks.js
Simple deep links to any selection of text on your website
...Here's an example of what one of these links looks like. It's intended mostly for blogs and other such websites, but it's relatively agnostic to the environment it's running in. People can select text on the site as the normally would, and when they do, the fragment identifier (the thing that comes after the # in the URL) changes. If they want to share the text they have selected, they simply copy the URL and send it to someone. When that person visits the URL, the same text that was originally selected will be selected and scrolled into view.
