Clearly, this is not a unique breakthrough: Twitter, with its tagline of "follow your interests", had already understood its maximum value proposition and was trying to tell me it would be most successfully utilized as an information consumption tool. I just missed the message, and had to learn that for myself. This realization has ultimately helped me considerably, to organize, personalize and maximize my news intake.

If you haven't yet, I do suggest giving Twitter a shot, approaching it the "right" way.
On a side note, I am getting better and more comfortable with my own Twitter output, as well:
