Jeremy had posted a small tutorial on creating the “possibly related stuff” search for Movable Type blogs and I converted it into a small plugin that can be downloaded here.
The plugin is really simple and it adds a link to stuff that is possibly related. I dont know how useful it will be for everyone, information is always good.
Please post bugs here. To install just copy to your wp-content/plugins folder and activate. This blog has a link generated for every permalinked page for testing.
