This is actually a really good "bright line" distinction between something being a forum and something being "social media". On any site (forum, S.M. or otherwise), comments or articles must necessarily be ranked top-to-bottom, where top usually is the most visible. How this ranking happens often is the main driver of what the site is like.
- Chronological (either first on top or last on top): Not social media
- Site-moderator curated: Not social media
- User-voted: Social media
- Algorithmic (usually based on some opaque measurement of engagement): Social media
