Here are the links to three useful blog posts and articles about twitter.
First up an article on how activity on twitter might help your presence in the google search engines:
“We struggle every day as authors to get the word out about what we do. It’s important to be firing on all cylinders. The agreement between Google and Twitter might help us in that endeavor. So, if you aren’t active on Twitter, maybe now is the time to reconsider. It will take a few months before the effect is noticed on Google, as the best estimate of the functionality taking place is sometime in the first half of the year. Happy tweeting!”

When it comes to the moment you can Tweet something promotional there’s some important things you can do to ensure you get the desired response, and don’t annoy your followers.
