Just an individual opinion but I see way less spam than I see on Reddit when I sort top past hour. I haven't seen any advertisements yet for t-shirts or mugs. I've seen a couple of meme channels that I have blocked. I've seen very little racist postings. I see some diverse political commentary. I have seen very little or no troll posting within comment chains.
I find the amount of people coming here and criticizing the activity pub protocols and the apps that are using them seem to have an agenda. We're living in an ecosystem that is basically getting its first real test. Tools will be built to address these things as time goes on.
Another thing people don't talk about is the amount of moderation that's needed on Reddit to keep it semi-usable. A lot of those moderators have now left and have been replaced with lower tier mods. A lot of the auto mod tools are going to stop working in a couple of weeks. This is only the beginning. I already see a large change in what shows up in Hot or r/all. A lot of us didn't like the way Reddit has become anyway. All it is now is a vehicle to push ads and it's no longer about community and discussion.
