Twitter is a social network and micro-blogging platform that allows you to send 140-character
“tweets”. With these tweets, you can let your friends know what you're up to, share links and
cool resources, communicate with your customers, drive traffic to your website, and much
more. According to the Twitter website, Twitter allows you to ask the question, “What are you
doing?” It was launched in 2006 by Jack Dorsey and in 2008/2009 it practically exploded in
popularity. It's extremely simple interface and ease of use is probably one of the reasons why
it has caught on like crazy.
