Unfortunately there are very few open review projects and none that people have tried to actually integrate into one of the OSM apps. It makes me rather disappointed as finding businesses and checking reviews is one of the most common uses I have for Google Maps and yet OSM cannot replace it.
We have a movement in Canada called “Every Child Matters” due to indigenous history. The most annoying thing to experience is the same idiots who complain about BLM commenting on this one. “Black Lives Matter? What the hell dude, ALL lives matter!” then 5 minutes later saying “Every Child Matters? No shit, what a stupid movement name!” Can’t win with these folks.
