I found this earlier and it is very simple to do, but not everyone is doing it.  Make twitter a lot easier to use.  You can link up any rss feed to your twitter account.

If your blog is not already set as an rss feed then go to Feedburner to set up an rss feed for your site.

Once you have done that then go to TwitterFeed, set up an account, then add your feed, give it a name and you are good to go.  You can add multiple twitter accounts as well as multiple feeds so if you have a friends blog that you would like to feed to your twitter account or another blog or some other feed then you are able to do this.  Between this and the blog import on Facebook (see earlier post http://imperiousdesign.com/blog/?p=31) you can truly automate a lot of your effort, then once a quarter compile your blog posts, add a little bit of fresh content and send them out as your newsletter.  You now only have to focus on one thing to generate social media and drive links to your website.

I hope this is beneficial to you and your business!
