As far as we can discern, the sole purpose of human existence is to kindle a light in the darkness of mere being. — Carl Jung
While Jung may have the collective unconscious to have a great signal-to-noise ratio, the part of the collective conscious that Twitter seems to have accessed has a poor signal-to-noise ratio. So, I may not be following you because:
Your stream of tweets is simply a catalog of your every waking moment. A constant bombardment of information eventually becomes noise. I don’t have time for that.
Your tweets are simply monotonous diatribes on a single topic. I left that behind when I left usenet. While others may find that endless catalog of links interesting, I’d rather google for the information when I need it.
Finally, blatant self-promotion doesn’t trip my trigger.
I’m looking for the art, poetry and interspection that occassionally winds its way through general morass. I want to read something that is funny, interesting, relevant, cute, or thought provoking. I use Twitter to be entertained and to meet people. So be a light in the darkness and I will follow.
