Thanks for the suggestion to try Crusoe. I'll check it out.
Guess I have a different objective to you. The odds of a random note being of interest to me when I want to review notes randomly is quite high.
I still don't understand why Evernote can't just give every note an index number and then use a random number generator to select the order in which they are displayed...
I'd love to see a feature which allowed me to browse through notes at random - kind of like flash cards. I keep archives of notes and articles, and this would be a great way to refresh my memory and revisit old ideas.
