“Twitter is a service for friends, family, and co–workers to communicate and stay connected through the exchange of quick, frequent answers to one simple question: What are you doing? Bloggers can use it as a mini-blogging tool. Developers can use the API to make Twitter tools of their own. Possibilities are endless!”

I think you really need to figure out which companion tools to use in order to derive benefit from this resource.

Examples:

cell phone texting
twhirl: “twhirl is a desktop twitter client, based on the Adobe AIR platform.“
IM
twitkit etc…

You also have to figure out some of the addons

@username =public replies to your followers/followed
#hashtags – a companion site that enables tagging of your tweets (I haven’t quite gotten it to work yet)
