Enable commenting on your posts via Twitter.
Posts will get a “Discuss on Twitter” button, which will prompt visitors to reply to the original tweet about the post, as well as a “View Discussions” button which will link to existing tweets about the post.
Each new post will be auto-tweeted (requires the <a href="https://wordpress.org/plugins/wp-to-twitter/" rel="ugc">WP to Twitter</a> plugin and a <a href="https://developer.twitter.com/" rel="nofollow ugc">Twitter Developer account</a>).

Discuss on Twitter

This plugin allows you to add Twitter-like @reply links to comments, including a preview of the comment replied to. 
When clicked, those links insert the author name and a link to the comment you are replying to in the textarea, and adds a Preview of the original comment to the @Reply (on hover using javascript).

I didn’t create anything new, and I do not claim so in any way. 
This plugin is just a feature I wanted and thought it could interest some other people.
