Advertising is meant to trigger subconscious reactions.

The lack of algorithms and the user base itself also contribute to how much nicer it is here.

If feels less "busy" more relaxed.

Less competitive, people seem more genuine like we aren't all just trying to impress each other or big note ourselves.

Rage bait rarely gets traction, discussions stay civil most of the time.
