I dearly miss the concept of circles in Twitter, both in incoming direction (filtering by what kind of stuff you'd want to read right now) and more important in outgoing direction (so I don't offend my fragile dev-o-sphere snowflake followers with manosphere or alt-right retweets).

Requires 2 things: - feature to classifying your followers into circles (unbeknownst to them) - feature to select target circle for a tweet/retweet/like (or, more comfortable, classify people I follow into the same circle, and making retweets/likes per-circle).

AFAICT, gab.ai does not have anything like this, either.
