A lot happened in the meantime, now we are Hive, we have DHF, and ... since the last HF there's a lot of change related to curation. Well, changes small, but their impact is significant. You no longer need to compete with bots or try front running. Human honest curators that are active enough (daily) can just vote whatever they like without losing on curation just because they are late. IMHO, currently it's all about discovery and that's a challenge to improve it.
