わさび » Archives » WordPress Related Entries plugin - a very nice little plugin that searches for related articles using MySQL's full-text index. Of course, this is only a fairly simple algorithm and the quality of results is nowhere near Google's level, but I installed it anyway. When you go to the detail page of a post (e.g., by clicking on the title), a list of up to 5 matching other articles is displayed.
I also expect this to give somewhat better positioning for various older posts - without having to remember to manually set a link to them every time (hey, most of the time I've forgotten about them myself!). And maybe it will also help people who come via search engines to find what they're looking for.
Besides, it's cool, and cool is good
