If 12 people upvote something I posted or said, that means that at least a third of those people actually genuinely considered what I said/shared.
If I share something that even reached 2 or 3 people... that is a lot of people. The absolute numbers don't mean much to me, honestly if even a single person genuinely reads an article I find interesting that I share and it impacts them, on a platform as cool as this... I feel good.
Now if I am posting/commenting something bitesize, something fluffy or flippantly fun, than 2 or 3 people reacting doesn't mean much, so it all really depends on the context.
