I have just set up TwitterFeed so that it will tweet any new Blog Post - this is a test.....assuming it works I will later expand on this and teach it.
Yes this does work very easily though the first posting takes about an hour to show up.
Simply sign up at www.TwitterFeed.com and go from there.
I should also point out that Twitter has some cool gadgets for you blog that are also easy to create
and add to the blog all from the Twitter page - once you click get code you can simply say - add to Blogger and they appear nicely as on the side of this blog.
