Whether this is intended or not, you can put a pre-existing article to the top of your website’s Atom or RSS feed by saving it as draft while it is being modified before restoring its status to live again. This is handy when you have got permanent articles that you are enhancing over the course of time and you want to give your visitors a reason to return and maybe even prompt search engines too. New articles will achieve this always but it’s nice to see that older articles don’t get lost in space either. This may be a hack but I am using Textpattern for permanent postings rather than blogging and am very happy to see the availability of the feature.
