The feature is now available to all of our users on LinkedIn to integrate a twitter account.
On LinkedIn
When you are signed in, check the Twitter box under your Network Updates box on the homepage and follow a few simple steps.
Clicking through the setup process will allow you to specify the Twitter account that you’d like to sync and/or display on your LinkedIn profile.
On Twitter
As part of the setup process, you can choose to either send all your tweets or select tweets from Twitter back to LinkedIn as a status update.
You can choose to share all or just tweets that you tag with #in at the end (similar to #fb for facebook)
