Libin: We wanted to make something for ourselves. The idea was to let you remember all the information coming at you in whatever way was easiest at the time, whether it was audio, images, text, web clips, or documents. One place where you can put everything and always be able to find it. We would take a picture of the white board and search for the words in it and find it.
Excellent interview with Evernote CEO Phil Libin -- a must-read if you're an Evernote fanatic as I am.
