NEVER MIND. Found one (The site is backup but it was down before for me): http://www.lab4games.net/zz85/blog/2005/05/27/loading-live-posts/#
Has anyone here created a plugin called "Live Posts" or tried for WP? I want to insert the latest post in the sidebar and from there when a user clicks the link, It will automatically appear with ajax. Similar to live archives plugin but this is live posts ;).
