LinkedIn users who want to share their Twitter messages on their profiles won"t have that option anymore, at least from one side of the equation. In a post on LinkedIn"s blog, the business oriented social networking service announced that this move was made due to tighter restrictions imposed by Twitter.
Twitter"s blog announced today, " ... we’ve already begun to more thoroughly enforce our Developer Rules of the Road with partners, for example with branding, and in the coming weeks, we will be introducing stricter guidelines around how the Twitter API is used."
As a consequence of those tighter guidelines. LinkedIn announced today:
Consistent with Twitter’s evolving platform efforts, Tweets will no longer be displayed on LinkedIn starting later today. We know many of you value Twitter as an additional way to broadcast professional content beyond your LinkedIn connections. Moving forward, you will still be able to share your updates with your Twitter audience by posting them on LinkedIn.
So in other words, if you have a LinkedIn account and a Twitter account and want one message to be displayed on both services, you cannot use Twitter to display that same message on your LinkedIn profile. However, you can still post a message on LinkedIn and share that message on your Twitter account.
