Bookmarks are the key to organizing our thought as embodied in the web — and a stepping stone to the web-enabled mind.

Making our mark on our world is arguably among the most important activities we can undertake. The drive to make our mark on this world is underpinned by our most passionate hopes. It affords us the promise of being able to be proud, saying to the world, “look, here’s what I did!”.

But making our mark serves another purpose too. It provides guidance for us in that it serves as a reminder for where we’ve been, where we are, and here we want to go.

We write lists of our goals, write diaries containing our innermost secrets, and highlight text we might need for an upcoming exam. It’s a very personal activity, and involves reorganizing and tagging the world to represent how we understand and feel about it. It reflects a complex array of phenomena in our mental state — our thoughts, perceptions, and feelings.
