I came across the Yet Another Related Posts Plugin again and decided to give it a try. The description says:

Yet Another Related Posts Plugin (YARPP) gives you a list of posts and/or pages related to the current entry, introducing the reader to other relevant content on your site

I have installed YARPP here and I am impressed by the result. Now the plugin suggests related posts and I don’t have to do that manually anymore when writing a new blog post.

YARPP can add related posts to your RSS feed too, a nice feature.
