I'll answer in a full-length post and tag you. But in a nutshell, I believe curation is about recognizing, giving preference to and assigning reward pool rewards (via upvotes) to works that add value to the ecosystem, Whereas Kurashun is clicking the vote button on anything that will give you an curation reward.
The curation system is still not perfect, but I choose the former over the latter because I think the by increasing the quality of the content here now, we might incentivize further increasing the quality of the content in the future and perhaps attract some new authors or just folks that would like to have a good conversation about interesting subjects in the comments section.
I already applaud the effort.
