Repetition. The front page algorithm frequently shows way too many posts from a single community, often in a row. It also tends to show me a lot of duplicated posts that have been reposted to multiple communities.

There needs to be a better mix in the way posts are selected. Popular communities should not be able to dominate the listing with multiple posts. The more posts they get to the front page, the more they should be down-weighted in order to give an equitable mix.

This complaint applies to All, Local, and Subscribed. If you don’t want to change the default algorithm, then perhaps add the new one as an option?

I wouldn’t worry about it too much. YouTube comments are the absolute bottom of the barrel in terms of quality engagement. They mostly exist to give people a place to vent when the video creator annoys them!
