If you're still not sure how Evernote works, you need to see this note of mine. After the NAPO-SFBA conference, I created a note to include every note taken, handout, and business card generated by the conference. This took just about 5 focused minutes. It's all been recycled. NONE of it came home with me. I see Evernote's greatest benefit being that it makes our information useful.
If I had neatly organized all of this into a file folder marked "NAPO_SFBA 2014 Conference," it would have been neat, but not useful.
