When a reply is made to a comment, a twitter notification (@twittername) will be sent to the original comment author to notify him/her of the reply. The notification will be sent from your Twitteraccount. 
This will allow the users to follow up on the comment and expand the conversation if desired.

CommentTweets

When a reply is made to a comment, a twitter notification (@twittername) will be sent to the original comment author to notify him/her of the reply.

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.
