Active Rain does what it takes to stay at the top of google weather it be adding the feature of Twitter so all your post can now update as tweets.
The twitter feed I have upload onto my Facebook page and that will post my blog on the big sites
ActiveRain post -> Twitter -> Facebook.
You can also go another step and add yor ActiveRain RSS to your Facebook.
Add your Activerain blog posts to your Facebook profile automatically
Facebook allows you to add the posts from any blog (including those on activerain) to your Facebook profile, which is a great way to get your activerain blog noticed. To do this, first install this Facebook app: http://www.Facebook.com/apps/application.php?id=5315590686. Follow the instructions of the application and enter your "rss feed" url which is http://activerain.com/blogs/username/rss (changing username to your activerain username) and every time you post something on Activerain, it will get posted automatically on your Facebook profile!
Now ActiveRain has did one better adding the Facebook like this button to every post on ActiveRain this will help to complete the circle and integrate ActiveRain even better with Facebook.
