Some great points here and a great comment, thanks!
As for the challenges here's how I've thought about it:
At first it would also have the community moderators active in curation, these people need to be vetted and trusted not to abuse the comment reward distribution system in their favor, but of course similar to everything else on Hive things are transparent so anyone could notice something shady happen at any time and alert others. Since the communities are at a growing stage and don't have all that many readers in the beginning, curators would help with comment upvotes so the bot takes those into account when distributing the post rewards as tips after posts pay out. After they've grown the moderators would be less active curating comments themselves and leave it to the author and the rest of readers.
Same here, community leaders could mute/downvote spam comments, luckily we have downvote mana now that can be utilized for those things and we don't see a lot of that around nowadays.
comment plagiarism might be difficult, lol, I know on reddit whenever a similar question is asked you can almost always find some similar answers at the top and I'm sure many just go and copy an older comment that did well for that subject, at least here you can't edit out your history so there's a higher chance to get busted for plagiarising someone else's replies if that's really something you start doing.
I wouldn't mind unique front-ends but it can't hurt to start building out the communities already.
Cool,😎 seems you have already thought out stuff. I agree to your every solution and they seem effective to me. A moderating team will cut out most of the mess. Including the redundant questions besides these challanges.
And yes, no harm in building the communities with this execution in place.
Also, I feel probably ratio can ve revised. Like instead of distributing 100% of rewards. How about leaving 10% or maybe 20 with the author. So people are encouraged to ask more relevant and thoughtful questions. Or may be a ratio or a better ratio can be decided after actually witnessing how things work out. So in any case, it would be good to put this in action and start as soon as possible. 👍
Also I have some other ideas, but they will probably streatch this too far out of its initial stage again. 😅 And might be relavant an year or years after. I am not sure.
But still to instill some food for thought, introducing anonimity to ask questions and write answers. Will unlock the doors to 1/3rd of crowd in need of non judgemental expression or personal counseling that flock at sites like quora or other forums. And that's why I vouched for a dedicated front end. Well I can talk about this more. But i guess this is a senstive topic, and even not sure if it is feasible. Also, a bunch can always present better opinions and unique perspectives than an individual. So it'd be better to also bring this into discussion in some future post. If and when you feel it's worth decompressing.
But for now Quorive 🤘, I'd love seeing it in execution and will participate.
