It appears that the content-sharing partnership forged by Twitter and LinkedIn in 2009 — like “peanut butter and chocolate,” according to LinkedIn’s blog post at the time — is no more.

LinkedIn informed its users in an email message this afternoon, “Twitter recently evolved its strategy and this will result in a change to the way Tweets appear in third-party applications. Starting today Tweets will no longer be displayed on LinkedIn.”

Or, in layman’s terms, this makes Twitter like that bitchy date who really makes you work for it by holding her purse while she goes to the bathroom.

If you want your LinkedIn updates going to Twitter, you can still do that. Here’s how: Write your update, check the box with the Twitter icon and hit “share.” It will push to both your LinkedIn and Twitter accounts, just like before. But if you compose something on Twitter, you’re going to have to repost that to LinkedIn, too.

Twitter’s consumer product chief Michael Sippey explains Twitter’s reasoning more over on their blog, mainly that they want to deliver a “consistent set of products and tools.”

But, as Owen Thomas at Business Insider points out, Twitter has increasingly been trying to control its content — less coming in, more going out. “What’s bizarre, though, is that Twitter just upgraded its own Facebook app,” Thomas writes. “Which crossposts tweets to users’ Facebook profiles — exactly what LinkedIn has been doing, with Twitter’s blessing, since 2009.”

And Mashable speculates on the move, too: “Perhaps Twitter wants to separate itself from the business networking company after the recent password breach in which 6 million LinkedIn passwords were stolen.”

What do you think? Good move or massive Internet snub?
