ince tweets are limited to a succinct 140 characters or less, services have popped up around the web that create short website addresses that you can share with your followers without using up too many precious characters in your tweet. These services are called “URL shorteners” because “URL” is the technical term for a web address. Typically, URL shorteners create very short addresses that automatically transfer anyone who clicks on them to the longer address of the page you want to share.
Yes, it's true. I used URL shorteners for posting in Micro Blogging.
