Twitter is indeed a powerful tool. I am beginning to realise its potential as an educational facet. In the article below, Jessica Hische explains in layman’s terms all about Twitter! Below is a link to the original article and I have also provided a PDF copy of the article that you can download.
From http://www.momthisishowtwitterworks.com/ by Jessica Hische.
“Twitter is an online social networking tool in which users post 140 character updates of what is going on in their lives along with links to things they think are interesting, funny, or useful to their followers (“following” being essentially what “friending” is on other sites). People use twitter in many ways, some as a newsfeed by following prominent people or networks, some as a pseudo-chatroom by limiting their followers and whom they follow to close friends and family, and some as a microblog for updating people about the work they are doing and their personal lives.”
