Here is something completely different, Jack Slocum has gone ahead and used Yahoo UI and YAHOO.ext to modify how comments are handled in WordPress. While it is not all that practical for most people, it is still a very interesting modification.
For quite some time I have wanted to upgrade my WordPress comments system. I had some free time yesterday so I decided to go through the WordPress internals and figure out how some of it worked. Before I knew what had happened, it was 3:00am and I had a working prototype. It worked so well in my preliminary testing, I decided to deploy it to my blog and see what you guys thought.22
I think it turned out to be a perfect example of what can be done in a very small amount of time with Yahoo UI and YAHOO.ext. In a day’s worth of work, I have completely transformed the comments system on this site. Around half of that time was spent on the user interface, and the other half modifying WordPress to do the things it needed to do on the backend.
Basically you can comment on a single paragraph allowing you to pinpoint the exact section you want to make a remark on. I would love to have the changed files, and modifications done up in a nice package for people to install, but no doubt after extensive testing we might just see that.
