A new free plugin to increase Engagement

Hi, I just read somewhere about a new plugin and a web service which provide some new features such as Comparison Box and argument box.

They also have a free plugin here. I tried it and I am getting good results so I thought of sharing it here.

The website name is Speakol - here is the link

And there plugin is here

Do you know if content created by Speakol is indexable by Google / search engines?

Looks interesting, but it probably wouldn't be of interest to anybody here unless search engines can see visitor comments.
