Generally the correct default, I think. And sometimes the correct non-option too.

I personally prefer to have them in many social media things (it's a hint for "this is popular enough that they won't even notice my contribution" vs "likely ~nobody else has seen this, maybe I should spread it"), and I think I manage to avoid the addictive parts pretty well... but it does still affect behavior (e.g. above, do I boost it or no?) and sometimes that's a net negative for the ecosystem.

(unintended but fittingly: ^ above is just barely under their 500 char limit. though this addition is not. I generally don't like small char limits, but to each their own)
