What Twitter does, in a simple and brilliant way, is to merge a number of interesting trends in social software usage – personal blogging, lightweight presence indicators, and instant messaging (IM) status messages – into a fascinating blend of ephemerality and permanence, both public and private.

Twitter is essentially a service. It has brought Internet communication to another level. It’s fantastic if you want to have a nice chat, or just to follow up on what friends and family are doing.

Twitter is really fun and cool sharing activities that you do with people who care or want to keep in touch with you. Your updates allow you to “tweet”, meaning anyone who follows you can find out whatever you’re doing and possibly learn more about you. Following friends allows you to see tweets that are submitted by them on your twitter site. It doesn’t matter how trivial your update is, the world wants to know!

Twitter can be used for many things. You can use it for a tumblelog. This works out very well, because it's extremely simple to submit “tweets”. You can use their web interface, which is just a simple text box, which is an easy to get things done. Then you can use your cell phone, by just texting, which is very convenient.

One thing people love the most is you can change the look and feel and customize the design of your twitter site such as, colours, background images and etcetera, but it's absolutely impossible to make it look as bad as some of the myspace pages you'll see out there.

In that respect, Twitterers resemble bloggers, except that most updates are rawer, with a more dashed-off flavour – which is to be expected, since they're also far shorter and more momentary than blog posts. This is the “social-networking and microblogging” site where you can read fascinating and mundane quick takes. Through twittering, the world can share their thoughts.
