The Jetpack Publicize feature is not working for LinkedIn anymore. My website is http://www.pilatesgymsd.com and there are publicize widgets on my blog articles.
To clarify, the little button shows up in the "share" section. What Jetpack is no longer doing is pushing content to my LinkedIn profile like it does for Facebook, Twitter, Tumblr, etc.
I think this may have been something LinkedIn has prohibited?
