What is Twitter?
Twitter is a service for friends, family, and co–workers to communicate and stay connected through the exchange of quick, frequent messages. People write short updates, often called “tweets” of 140 characters or fewer. These messages are posted to your profile or your blog, sent to your followers, and are searchable on Twitter search.
What does it mean to follow someone on Twitter?
Following someone simply means receiving their Twitter updates. When you follow someone, every time they post a new message, it will appear on your Twitter home page. New messages are added to your home page as people post them, so you always get the updates in real time. When you log in, you can see what the latest updates are.

What Is Facebook?
Facebook is a great way to meet friends and keep up on what they are doing. Once you add a friend to your Facebook friend list you will always know when they are adding things to their blog or updating their profile. Join Facebook groups to meet people like you, or browse the profiles to find new friends. Facebook’s classmates and co-worker search is good for finding friends too.
Users can join networks organized by city, workplace, school, and region to connect and interact with other people. People can also add friends and send them messages, and update their personal profile to notify friends about themselves.
