I really enjoy incentive systems and reward functions. Sometimes a good reward function for humans is visually enhanced by levels, virtual badges, rare emotes or color.

Tips could have some kind of small img depending on value. I know many do not like visually enhanced gaming like reward extra bling because it distracts.

Maybe there is a clean way to make the upvote sats and tips visually more dominant and pleasing without overloading.

I really like the red thing popping up from time to time in the upper corner and the favicon. It triggers me a lot. Somhow i was trained to watch out for it.
