Broadly, yes, and as a result its a lot smaller because I'm only carrying a few cards at any given time.

Any page or spread you might have in a notebook can easily be turned into an individual card. The one hard and fast rule I use is: one dated note card a day for events and to do items. You can get an idea about some of the other specific practices in a few of my responses to other questions in the original posts response threads.

I also don't have to worry about losing everything at once if my notebook is lost or goes missing, just a day or two's reminders. I have lost six months' worth of bujo in the past while traveling, but have yet to loose a single index card.
