We do the following on the internet:

  1. Consume content
  2. Communicate
  3. Collaborate
  4. Produce content

I’d say the breakdown of the amount of each activity is something like 80/10/8/2, simplistically speaking (ignoring overlap, etc).

(…)

#4 is slowly having a larger and larger overlap with the others, so much so that we produce content as we consume – tweets, comments, facebook ’likes’, etc.
