One of the good things about having a blog based on WordPress is that people have written lots of cool plugins for it.
Alex, at the Wasabi blog, has one called Related Entries which does a search for other posts on your blog that might be relevant to the one you’re looking at. I’ve tweaked it a bit and have installed it, as an experiment, on the individual post pages here (which you can always get to by clicking on the title of a post).
If you’re looking at this entry on the summary page, for example, click on the title and it will take you to the post’s own page, and the plugin will suggest some of my other posts about WordPress and blogging. Quite sweet!
Update – the plugin has moved and can now be found here
