Twitter is a ‘microblogging’ system that allows me to send and receive short posts called tweets.
Tweets can be up to 140 characters long and can include links to relevant websites and resources. Twitter users follow other users.
If I follow someone I can see their tweets in my twitter ‘timeline’. I can choose to follow people and organizations with similar academic and personal interests to me. I can create my own tweets or I can retweet information that has been tweeted by others. Retweeting means that information can be shared quickly and efficiently with a large number of people.
