Today, Twitter and LinkedIn joined forces in an agreement that will allow users of both services to sync their status updates.
LinkedIn will now allow you to update your status on your LinkedIn profile and then share the message automatically to Twitter. To enable to enable the cross posting feature, you just need to click the new Twitter box under your Network Updates box on the homepage and sync with your Twitter account (via oAuth).
The integration works the other way as well. You can also share Tweets to your LinkedIn profile from Twitter or any other client by adding the hashtag “#in” or “li”. As part of the setup process on LinkedIn, you can choose to either send all your tweets or select tweets that have the hashtag “in” from Twitter back to LinkedIn as a status update. You can also import your Twitter stream into your profile now, which is also an op-in feature. So your profile will show a “Recent Tweets” section that will include a real-time stream of your Tweets.
