We live in a three-dimensional world. Our hands are designed for moving and rotating objects in three dimensions, for picking up objects and placing them over, under, beside, and inside each other. No creature on earth has a dexterity that compares to ours.
The next time you make a sandwich, pay attention to your hands. Seriously! Notice the myriad little tricks your fingers have for manipulating the ingredients and the utensils and all the other objects involved in this enterprise. Then compare your experience to sliding around Pictures Under Glass.
Did the Internet community peak at bookmarks? Asked in a different and perhaps more complete way: just as technologies like RSS and email in their purest forms are hard to beat even as technology marches forward, what better technology exists to keep track of information on the ever-expanding Internet than bookmarks? Taken a step further, what better way to share the bookmarked information than a site of your own? As such, I‘ve been reading, which is why I write now.
Working in and having a passion for libraries, I am struck by the fact that the way bookmarks work in the physical world is not directly analogous to bookmarks in the digital world. Bookmarks in the digital world are instead like dog-eared pages or highlighted passages; if you think of the Internet as a single tome, that is. In any case, anything that moves you to deface a book should probably be shared or become immortalized in some other way than just a reference for a future version of yourself.
