Hello Ryan and welcome to Dev, it's great to have you here.
The unicorn is open to interpretation and there have been a few threads with others thoughts over the years:
You can react to your own posts with the heart, unicorn and bookmark emoji if you wish. When you post a comment you react with a heart by default.
The reactions on desktop should sit on the left hand side when viewing a post, when you resize the browser narrow enough they will shift to the bottom of the screen. Is that what you are seeing or do we need to submit a bug report?
Oh, I see the reactions on the bottom now. Thank you. I don't know I didn't see them before :D
