I am building a news feed and I thought of changing the location of the comments to be on the side. Besides Medium that does it more for footnotes, I didn't see a website that has real discussions on the right side of the post instead of the bottom. Especially in the newsfeed itself.
For me it looks readable and intuitive, but I want to be sure I am not breaking any UX rule.
Here's an image:
When clicking on the comments icon, the post shifts to the left and the comments column fades in quickly from the right.
