Twitter is a social platform based on microblogs and the possibility to send and receive short messages (up to 140 characters) called tweets.
Since this platform currently has around 100 million users, software developers have started to create desktop applications that will enable them to keep track of the tweets they receive and also allow them to send messages.
One can also rely on some Twitter notifiers to monitor more than one account.
Twitter clients can also be used for choosing the people one wants to follow or un-follow.
