Twitterfeed (http://twitterfeed.com) is a service that publishes tweets on your behalf (that is, using your Twitter account) from feeds (for instance, from your blog) you provide to it. This is cool but the really nice thing is that its name paints a more restrictive picture than is reality: Twitterfeed can also publish updates on your behalf to Facebook and LinkedIn. And each of these is optional so you can publish to any or all of Twitter, Facebook, and LinkedIn.
I've chosen to set up Twitterfeed to publish to all of Twitter, Facebook, and LinkedIn. So that means that a notification about this, my first blog post written since I began using Twitterfeed, should get published out to my Twitter account, my Facebook account, and my LinkedIn account.
Cool, huh? How do you get updates about your blog posts out to Twitter, Facebook, and LinkedIn?
