There's a reason it's secret
Yes, I did try to set up my Evernote account to work the Secret Weapon. It did not work for me... As I was creating the numerous tags and figuring out how to manipulate the date so you can add some sort of reminder-functionality, I suddenly realised:
It takes ages, and feels like a workaround rather than a properly designed system. It is really cleaver and if you have the time it may work for you. For me, I think that if you're going to use a virtual system, then there are plenty of options which will automatically do what you have to manually do in Evernote.
Evernote is superb, but the Secret Weapon implementation just took me too far into the mechanics of the system and away from organising my life! Hope this helps...
