list of related posts

Hello again!

I’m trying to put a list of related posts into my single.php template file, hopefully correlating the top few posts with the most similar tags. Does anybody have a good method for doing this?

For example, lets say I have a post called “Dalmation”, and it has the tags “dog, firetruck, spots.” If I were to view this post, I’m hoping that it would show me the contents of the post, followed by a listing of the top 10 similar posts, ranked by the number of shared tags.

Any thoughts?

Thanks!
Adam
