Facebook vs Twitter
Facebook is a social utility that connects people with friends and others who work, study and live around them. Twitter on the other hand is a free social networking and micro-blogging service that enables its users to send and read messages known as tweets. Tweets are text-based posts of up to 140 characters displayed on the author’s profile page and delivered to the author’s subscribers who are known as followers.
