SpeakUp: Let Your Voice B Heard от SpeakUp Software

SpeakUp is a browser extension that opens a sidebar containing a discussion forum where you can discuss and comment on the article you're reading. You can use SpeakUp on any web page, but particularly news articles, blog posts, and YouTube videos that don't have a comment section. Your comments will be seen by other readers, who will be able to upvote, reply, and recommend.

To open the SpeakUp sidebar, click the red/blue bubble S icon on the browser extensions menu. To change extension settings, right click on the icon and select Options.

SpeakUp uses Disqus comment thread software.
