Hello! A couple of friends and I built a Medium style tooltip that bloggers can add to their blog, which allows their readers to highlight and share specific phrases to social media. It should help increase site shares and help bloggers find out what their users are highlighting/sharing. It is completely Free, forever.
You can find it here: https://wordpress.org/plugins/highly/ or search for Highly – Highlight And Share Social Media Plugin, in the WordPress directory and click “Install".
Let me know what you think!
