That's true. I do wish the Discover algorithm were open, but I understand that can open it up to abuse. So far it mostly just shows me nice things. There was no point with Twitter's algorithmic feed when I could say that.

I can't speak to any secret motivations but it seems like the folks running it care about making a nice place for people to hang out. We've seen how a desire to not be evil can clash with a desire to make money, but I remain optimistic.
