Extension:SectionDisqus

The SectionDisqus extension adds a "Discuss" button next to the "Edit" button of every section (including subsections), that when clicked, opens a Disqus thread for that section, inside a jQuery UI dialog (similar to a lightbox). In other words, this extension assigns a different Disqus thread to each section, allowing to discuss each section individually.

Warning! When a user changes the title of a section, the discussion associated with it will be lost, or more precisely, get unlinked. This is due to the way Disqus works. Disqus tracks discussions by associating them with a unique identifier, which is usually the URL of the page with the discussion. But because this extension allows for many discussions in the same page, a different identifier needs to be provided for each. The way the extension accomplishes this is by appending the section title to the URL. As a consequence, when the section title changes, the discussion linked to it will change too. If you can think of a solution to this problem, please let me know, or better yet, fix it yourself. ;-)
