Twitter in Education:Spreading the Word

I have found it quite a difficult task to spread the word about how useful Twitter can be as a networking tool. After Twitter made the headlines a few times over the last couple of months, I thought maybe my task would become easier. Unfortunately, it has not been the case. Somehow, a lot of Twitter users have come out of it appearing as self-obsessed superficial people.
However, some documents such as this wonderful Twitter Handbook for Teachers breaks the trend:

Thank you for showing that Twitter can be an invaluable tool in Education.
