I'm implementing blog-to-twitter support in my blog, that is the ability to surface automatically on twitter the title and url of every post in my blog. As I have twitter to facebook integration installed, this will also be forwards to my facebook account.
Not sure if this would work, as this is an experimental post. Also, I might have to experiment with an URL shortening service, as http://blog.marcocantu.com/blog is quite long for a prefix to the actual link. My blog is powered by a custom scripting language we call GXI (the last two letters stand for 'Xml Interpreter'), so all I had to do was to add an HTTP call to the script posting to the blog, pointing to http://twitter.com/statuses/update.xml and providing a proper status string.
If this works, next I'll do the opposite, that is add my tweets to my blog, both as a blog post with a weekly summary of my tweets and by displaying the last tweets on the blog home page. Ready, set , go.
