I feel I am being brainwashed, but in a healthy, I-know-this-will-benefit-me-some-day kind of way.
I believe everything2 wants to reshape the world as reference librarians! Think about it, in order to write or review a node, you have to think of information and evaluate its worth to your audience, its source, and the best way to disseminate it. Then you have to think of as many related ideas/things/people/places as you can and how they all relate to each other, (cross referencing).
Finally, you organize your information and contribute it to a database, (e2). Just like a reference librarian (except for the adding to the database part).

I am still left wondering though, why reference librarians? This is all good brain exercise, I admit...all that cross referencing builds up dendrite networks in our noodles.
But, is it some altruistic desire to make us more competent at taking care of ourselves? Are we being prepared for alien enslavement on a planet with no system of organization?
