I definitely agree that it's really important to keep making improvements and suggestions. The trouble though, from my understanding, is that even if one instance/platform has privacy settings, it will still by necessity broadcast all of its user interactions. So that data is publically available, you would just have to switch to an instance with less privacy or make your own tools to access it.

I also don't like votes being public, but I understand that the Fediverse just isn't built for that kind of privacy. It definitely makes me more hesitant to engage though. I can imagine that examining a user's voting patterns could reveal a lot of potentially sensitive information about them, especially if the user wasn't aware votes are public. Sometimes I see posts that are very relevant to something real-life or local that's going on with me, but I wouldn't want any random user to make the connection, so I just don't engage.

I reread my favs about once a year. Sometimes the point you're at in life just makes a book hit completely different. I also get a rush of nostalgia from revisiting books that can be pretty pleasant.
