I never retweet stuff. To me that is the equivalent of mass email forwards and god I hate those.
Is it time for me to feel weird now or is it just the world that has gone crazy over some new emperor's clothes?
Guess my friends are more interested in posting original stuff than plugging content, and I'm pretty happy about that. If it's on their site, my RSS reader checks the internet 400x more times a day than I check twitter myself.
I think some twitter "power users" are oblivious to the fact that to everyone else it doesn't have to be the end all be all new everything communication platform it is to them. Me at least, I'm fully open about my ignorance about other uses :)
The formal retweet structure lets you build a true/formally defined social graph.
