The Custom Rel WordPress Plugin
Starting with version 2.8, WordPress automatically puts relational link tags in the heads of posts. This is not a bad thing at all. Not only are they standards compliant, but they can improve browser performance due to prefetching of the linked pages.
So how does WordPress pick the next and previous posts for the links? It links to the next and previous posts chronologically. Now if your blog is single-subject, that may be just fine. But if you have multiple categories, this may mean that the links are not ideal. In fact, even if you don’t factor in categories, some posts are simply more long-term than others. For example, WordPress want to link my post about the TTFTitles Wordpress Plugin to a post about being rejected from BlogRush. Given that TTFTitles is still widely used, but BlogRush doesn’t even exist anymore, it seems like a poor link choice has been made.
Here’s where the Custom Rel WordPress Plugin comes in. This plugin lets your override WordPress’s choices with your own. You get a nice new sidebar box on your post edit form:

Type in what you want to link to and away you go.
Enjoy.





would it be possible to add the plugin but when left blank having no links added instead of the poorly chosen ones by wordpress??
Right now, blank means default behavior. Maybe I can add a checkbox to determine whether it should use default behavior or leave them blank if no custom info is available.
