I have seen things like this on so many blogs lately, and I still think it is really interesting, and a decent use of AJAX. I have yet to impliment it on any of my sites as it was difficult to do, but now with the Inline Ajax Comments plugin, I might have to give it a go.
This plugin allows for the ability to expand the comments of a post below the main post content using ajax.
- comments are downloaded once the user clicks the “show comments” link
- subsequent show/hide actions use the already cached comments
- separate css stylesheet for easy customization
- easy installation into any theme
