What does the steem icon next to the article title means?

I know this is not exactly an article to deliver direct content, but I would like ask a question since FAQ does not seem to include such information.

Hopefully, others might have the same question, so I hope this article will be a source of information in general.

I made a post earlier and I noticed the icon of steem next to the title - you can see it below circled and pointed with the arrow.

I then noticed it on other article titles as well, but not to all of them.

So the questions are:

• What does it mean?
• Can we do anything with it?
• How often does it appear?

You are more than welcome to answer!
