Share blog postings with LinkedIn?

Hi there,
There is a plugin to automatically share your postings with your FaceBook account. Is there something like that for LinkedIn, so I can share postings from my own hosted WP-site there as well? There are many plugins, which add some sort of sharing option on your blog, but you have to actively use those to share, unlike the FaceBook plugin.
I seem to recall something like that exists for my WP.com blog, but it seems to have disappeared.

TIA,
