TWITTER: The social media network based on 140-character micro-blog posts. Users post short updates that can be seen by anyone, even if they are not logged into the site. Posts can only include text and links; any multimedia content (photos, video, audio) must be linked to. The people who follow you will see your updates in their timeline when they log in. Unlike with Facebook, you do not have to confirm or reciprocate the follower connection, meaning people can follow your updates without you have to see theirs.

Direct Message: A way to privately message someone you follow.
FF: #FF stands for “Follow Friday.” Twitter users often suggest who others should follow on Fridays by tweeting with the hashtag #FF
Handle: A user’s “Twitter handle” is the username they have selected and the accompanying URL, like so: http://twitter.com/username.
