Most of the Stack Exchange sites have their own icons for badges. Why don't we have unique icons for badges in our OpenData site?
No, most Stack Exchange sites don't have their own icons; only the ones with a custom design do. Usually, such a design happens at some point after graduation from the beta phase (but it takes a while, given the shortage of designers). Open Data is currently still a beta site and with 1.7 questions per day it will take a while.
Does graduation from the beta depends on the "Number of questions per Day"?– Orophile ModJul 22, 2020 at 10:36
It did, you needed ~10 questions per day, but a while ago, a couple of very old sites were graduated anyway. But they're at the bottom of the list when it comes to custom designs. Jul 22, 2020 at 10:55
