The Side Chatter is an interesting and fun way to chat and share insights with other people who are reading the same article as you are. If you're reading an article about a trending topic, for example, you can use Side Chatter to find other people who are interested in that topic and to discover insights that you might not have known otherwise.

You can click on the icon to activate the Side Chatter. You can then start a discussion with the other people who are using Side Chatter, even if they are reading different articles.
