Other work has shown that while the ability of light to produce a phase advance contributes to its clinical efficacy, this is not limited to subjects who are phase delayed to start with.

When you subscribe to a Smart List, all the posts from the accounts on that list will show up at the top of your screen, as a feed. That’s the “firehose”, nothing removed. By default, Smart Lists you subscribe to also show up in your For You feed. **In For You, we only show the posts that have engagement (likes, reposts, replies), so you won’t see *all* the posts from that list, just the best ones**. That’s a super simple algorithm (“only show posts from this list that have at least 2 likes, replies or reposts”).
