Feel free to use this concept of "troll," I think it will come in handy as we navigate this strange new world of "social media."
Here is an interesting and mildly humorous image I found on the 'net, I would recommend that it be posted in different contexts and message boards to reinforce certain ideas.
This social communication thing is coming along well! You can talk to people all over the world, basically instantly!
I have nothing but optimism for the future - where will it go next?
