What exactly is Twitter and how is it used? How does it work?

[LoLo]

On Twitter you have an account where on the home page you post thoughts, news, anything you want under 140 characters long. You can follow people so their tweets will show up on your homepage, and people can follow you and they will see your tweets.

As Twitter puts it:
Twitter can give a voice to even the weakest signals because of its simplicity. Users can access Twitter on powerful broadband connections via a video game console or through faint connections in rural areas via SMS on a simple mobile phone. You can also access Twitter through more than 50,000 third-party Internet and mobile applications.

Just remember, how you use Twitter is completely up to you. Follow hundreds of people. Follow a dozen. Post every hour. Post never. Search for your favorite topics and create lists. Or not. You are in control on Twitter.

You can also use Twitter for your business or band.
