I don't know.

Whether you/we like it or not, Steem is a stake based system. The largest stakeholders are going to have the most influence over what gets rewarded. Historically we have not done a good job at getting the large stakeholders (who's votes matter most) to pay attention to "the little guy".

One of the main goals of HF21 is to get the more larger stakeholders actively participating in curation. Whether they decide to curate posts or comments or both remains to be seen. I know in the past, @blocktrades has done a lot of comment curating.
