@ireneista My view is that this provide-metadata approach to promotion is the best possible approach.
1) It doesn't demand that anyone consume (since most clients allow hiding/controlling display of said metadata)
2) If done meaningfully, it provides the potentially-interested with a middle ground of information (‘i wrote a thing' versus 'here is a taste of this thing' versus 'read this whole thing’) that is helpful when making decisions about what to spend time digesting
