Aditya's latest hack is an interesting one, both because of what it does, and as an illustration of the limits of user-authored modifications. Aditya's asynchronous backlinks hack works on the list of backlinks in your post footer, and will open a great-looking ajax window containing the contents of the backlinking post in response to a single click. A double click will do what it usually does, & load the whole post.
To see this in action, load Aditya's Native Blog Search post, & single-click any of the internal links. These are:
Note that this won't load samples of external posts, because apparently Ajax can only fetch content from the same domain as the request, but even as an internal tool this is a huge step forward in consolidating content and presenting a coherent set of information, especially if your blog is a series of interlinked and evolving posts that build on one another.
Update: Looks like Adi has enhanced the way that the backlinks display, so that they write out an author name as well as the post title. This makes it much easier to tell which ones are internal links, and looks pretty darn cool. Good call!
