This one is big: Twitter just let you auto-follow your Facebook friends.

According to a post on Mashable, Twitter has just let you get face to face with Facebook friends, via new Facebook and LinkedIn applications.

You’ll be able to access the new Facebook application from this link, and then integrate your Twitter feed directly into Facebook.  The idea is huge, and could be the next major growth spurt for Twitter.

From the Twitter Blog:

The app also lets you post your Tweets to your Facebook profile and now, to one of your Facebook pages too. With the Tweets application by LinkedIn, you can see which of your LinkedIn connections are on Twitter and follow the ones you choose right from the app. The app also lets you save your LinkedIn connections as a list, post your Tweets to LinkedIn, and add your Twitter account to your LinkedIn profile.

Could this be the a nail in the coffin to services such as TweetDeck?  Only time will tell, but it certainly will be releasing a lot of work from people who use both services primarily for status updates.

You’ll need to check your Facebook settings, as early reports are showing a number of people (myself included) that cannot get the Twitter application to be allowed on Facebook.  The common message is that Facebook has blocked the feature.

We’re keeping an eye on this, and will let you know what we find.
