Web users became accustomed to looking for the little lock that browser UIs reward sites using SSL with.
I’m trying to get into the habit of looking at the Brave logo on the top-right to see if there is a number there, and when there is none I try to make a mental note of “nice, this website respects me, I should be kind to them.”
I’m thinking Brave could reward sites with no ads/trackers/etc. with something special as well. Maybe add a little shine to the lion, or something that says “zero” that is not just the absence of a number.
