What are mentions? They are a way to reference another user in your post. They are created by adding @ at the beginning of the word. In this way, you can find and tag the user in your text. Someone who has been mentioned will get a notification and might see your post. That is why this is a great tool to boost activity on your account.
Mentions are supported only by Twitter.
