So a boost is more of a sort of "revive necrothread" than anything else, and only serves to give visibility to content that is no longer on people's radar?
if not, what is the point of me boosting a comment someone else made 5 minutes ago? Is it because people who might follow me but not subscribe to the thread the comment was in, would otherwise not see it? So like, it's retweeting it to bring attention of that comment to my social circle?
