It wasn't me who remember this, it's the blog which recorded this. The daily del.icio.us blog post didn't come through last night so I searched here and found this earlier post about how to set it up.
I may have to edit the "thingy" again.
I have also added a feedburner's animated number of reader display at the footer. As I have an account with them I may consider just providing their feeds in here instead so many others at subscription page. RSS 2.0 is now becoming the standard therefore any news reader aggregators should be able to use this standard feed protocol.
