This plugin is really a nice find and allows any WordPress site to have their blog posts content and comments posted on Linkedin. You can also answer someone else comments in your WordPress article, it will also be displayed on Linkedin. A neat little hack to push existing and old content at the top of the Linkedin feed, sweet!
I invite you to test their website demo to have an idea.
Perfect for people publishing their B2B content on Linkedin.
And now that they allow multi-stacking for unlimited sites, it will be a nice service to sell to consultants and entrepreneurs.
Happy launch!
