When it comes to using blogs or wikis or Friendster, i'm not a user. I'm not following a prescribed usage pattern. I am a producer, a consumer, and a user. I may use a blogging tool, but i don't use a blog; am i a blog user? I may use Friendster to surf profiles, but as i create one, am i a Friendster user? What happens when i fundamentally alter the tool and the content in my use of the software?
