Feed your blog to twitter with ease
I recently came across an innovative service called 'TwitterFeed'. It helps you to update your Twitter and Facebook with the recent blog posts. It is quite simple. Create an account through a federated signon service like OpenID. Your favorite Google Account should help you get started through. Authorize TwitterFeeder to access your Twitter account and provide the necessary RSS URLs of your blog.
And every one hour your blogs would be monitored and new posts would be updated to the Twitter. I believe it supports Facebook too.
