@mike Algorithmic timelines are actually two things mashed together:
1. A filter, prioritising the most popular posts from the people you follow, which is meant to keep the entertainment value high
2. A recommendation engine, which is meant to aid in discovery
We can probably do without the first. The second gets to the huge discoverability problem on Mastodon. People don't know who to follow or how to find stuff that's interesting to them, and they often give up.
