A plugin to AJAX-ify any element on your blog and allow a visitor to drag and drop that element. Not sure of practicality, but in the trend to make things oh so web 2.0, this is just another tool for WP users to employ. And kudos to the author for getting the spirit of the community and sharing another of his creations.
It’s really practical for comment forms but other then that it’s too much for my site. But I’m sure we’ll see a lot of people use it.
