TwitterMyRSS.com uses Twitter to tweet the contents of an RSS feed automatically.

Why duplicate work by adding news articles to your RSS feeds and then have to do it all over again for your Twitter account? The good news is that you can now simply use twittermyrss.com to automatically post your RSS feeds as Tweets on your Twitter account!

You can also use it to autotweet news that your Twitter followers may be interested in using simple keywords. e.g. "Twitter Tools"

The even better news is that it takes less than a minute to setup and it's FREE to use!!!

P.S. It doesn't affect the normal use of your Twitter account either so you can still use that just as you always have.
