I actually came to this post while hunting for some Django info (shame your post got ripped off on that other site) but currently I’m running Wordpress too. I found another great ‘related entries’ plugin called ‘Similar Posts‘ — I’ve found it to be very good, and it is actually built on the Related Posts plugin but extends the algorithms used to find matching posts. It might be worth checking out — I’m running it at the moment and am very happy with it
