If you haven’t updated your Sharedaddy WordPress plugin recently, it might a good time to do so because they’ve just added Linkedin as another sharing service. It’s quite useful if you’re running a business or professional related blog or site. Note that as far as we can tell, the Jetpack version of Shareaddy hasn’t been updated with the Linkedin share button yet. Once you’ve gotten the latest copy of Sharedaddy, add Linkedin by going to Settings -> Sharing and drag down the Linkedin sharing button down to “Enabled Services.”
And make sure to click on “Save Changes,”
If you haven’t chosen a social sharing plugin, give Sharedaddy a try.
