imho, you only need one reference : http://headrush.typepad.com/ http://headrush.typepad.com/ Kathy Sierra is the goddess of techniques in bringing out user happiness. I would suggest you go back to the archives and read from the first blog post (the last posts are a distraction for your objective) In addition, if you have spare time to read "The Humane Interface" by Jef Raskin is an awesome read. edit: I understand you are looking for technical suggestions. Nevertheless, Kathy does talk about "kick ass" manuals.
