Twitter has served as an on again, off again relationship. I started following celebs and got bored fairly quickly. I didn't have any friends on Twitter so left for a year or so. This summer I set a goal to learn more about it and did ok. I engaged in a chat and was excited to be retweeted internationally. I started back to work and looked at Twitter casually.
Now it seems that it is a stream of useful web tools and resources. I believe that Twitter can serve as both an interactive learning environment where we push each others thinking and and a simple resource bank. It's up to us to decide whether or not the benefits outweigh the costs. Are we willing to work to build our own professional learning network?
