If you use FeedBurner and post your latest garden blog posts to Twitter manually things have just gotten easier. FeedBurner now automatically posts your latest update to Twitter. All you need to do is connect your Twitter account to your feed and Google will automatically publish new posts to your Twitter account. It even uses Google's new URL shortner: http://goo.gl/
It is easy to set up just follow a couple of steps shown in Google's Adsense for Feeds blog post.
Update: After using this feature I have to say I'm really impressed!
