Hi Nicholas, Posts should be easy to "read" and users should be able to go trough all replies, focusing on the content of the feedback, without any visual distractions. Users can have any kind of disability or special powers like visually impaired, any form of autism, Asperger syndrome, etc ... When people are reading posts and replies, they should be able to read content easily, filter easy post content from other design elements and be able to distinguish different posts and replies. It's always important to apply a "visual hierarchy" in any design. Important elements like the content of the posts should pop out, other less important stuff should be visual less noticeable. Creating a visual hierarchy can be achieved using simple techniques like font size, color tints, using background colors, etc... More info: https://en.wikipedia.org/wiki/Visual_hierarchy
