I feel like the straight boosting of a root note is a bit of a faux pas. This is especially true when the note is big/long or if the noter is well followed (eg Odell, Jack, Gigi).

The clear exceptions I can see (there may be more - context is key):

- an old, forgotten note that you think is relevant

- a reply note that has value on it's own (without context)

- a new verified Nostr user that doesn't have a following yet

- if you're going to add some context agree or diagree (quote note)

You can do it, but if you keep cluttering my feed, I'll eventually either quietly unfollow you or mute you. I'm pretty tolerant & it would take a lot for me to get to that point, but we all have a line. We've also all probably done it & there are no take backs here.

There will be a bit of an eternal September as Nostr goes parabolic & we create our unique culture.
