A huge problem with Twitter for some is understanding who is getting the message. Remember Twitter is Social Media and is based on social interaction. If you walked into an auditorium full of people and started talking without engaging someone first, no one would be listening. You would be talking out loud to yourself.  If you introduced yourself to someone and then began a conversation you now have someone listening and interacting. You would then do the same with a second, third, and fourth person. You have connected with those people and selected them as persons you may interact with, and they have selected you as well, based on your intelligent contributions to the discussion. As that works in life, so it works in Twitter.

Twitter is only one component of a comprehensive PLN. There are many Social Media applications that serve educators well for communication, collaboration, and creation. All of these applications are constantly evolving or disappearing, to be replaced by new applications. We need to buy into the method and not the tool. Tools change, but learning continues. To be better educators we need to be better learners.
