@Gargron So how about the ability for "commented boosts": you can attach a reply to your boost, so that your timeline afterwards shows your reply, with the boosted post as a "quote".
That way you would still reply inside the thread (ie. talk _to_ the original poster, rather than _about_ them), and you would boost the original post; but your followers would mainly see your comment (and also the boosted post, for context).
