Random midnight thought.
Likes and reactions seem useful both for the post’s author and other users. It’s important to know, especially for users newly arrived on a topic, which posts got traction, were emphasized by the community and are worth reading.
Conversely, boosts feel to me more valuable to the post’s author than the community. They are a like a guestbook. They’ll please the author but might be of low value for everyone else. People read guestbook out of curiosity, not to be enlightened.
In this regard, perhaps the boosts visibility should be a different for the post’s author (more boosts visible by default perhaps?) than other users.
Happy to hear opinions on this.
