Tvitter is so popular today. I honestly use it just for that. But many people are in it to recognize a good idea and know how to use it. As a developer the first thing that interested me is the API (http://dev.twitter.com/) that comes from Tvitter. By the way, I found very interesting widgets that are easy to use and can easily be placed on your site.
You do not need any programming skills. Follow the instructions and fill out a simple form. Custommize look and feel and within seconds you have Twitter widget. Copy the generated code into your page and that’s all. Widget can be found at the following address http://twitter.com/goodies/widgets
