I've talked about one of these in the past, the reblogrewarder, but if you don't wanna go and read a 1+ year old post right now, here's a quick rundown:
A service that counts the collective active stake that follows an account.
When that account reblogs a post, it takes a snapshot of the current pending rewards at reblog.
If the post ends up getting more rewards from active accounts following the reblogger, it counts these as points towards the reblogger.
If author has beneficiaries sent to "@reblogrewarder" - similar to @commentrewarder, it would give a % of those rewards to the reblogger.
This means that the author is still in charge of how much rewards they wanna forfeit towards incentivized reblogging. The reblogger's own vote doesn't count to avoid abuse. If the rebloggers start spamming, they may risk getting unfollowed. The idea is basically to reward good reblogs and remind people that reblogging is a valuable thing we may often forget to use and if used well could direct a lot of value to where it is deserving - making reblog curation more powerful for those doing it well.
The other idea is a forever staked account, this could be done with multisig of many large stakeholders who'll be around for a long time, but doesn't matter much if they will or won't be as the idea is that this account will never unstake the rewards it generate.
How is this different from burnposts or hbdstabilizer posts? Well, the difference is that this account would also compete with active curation rewards vs just author rewards. It could also curate itself, although the curation would yet to be determined how it's done or evolve over time.
How to fund this account?
Simple comment rewards similar to hbdstabilizer and burn posts could work - or:
accepting stake/delegations while offering the stakers and delegators some power in who they vote and don't vote, with a curation team to maintain curation principles and requirements in place. Compared to some of the current projects that may be doing the same thing, there'd be more oversight on who's "buying" votes for who and what content. But what makes this project unique is that there's a provable way that this account will never randomly "quit" or unstake all the rewards it has received so far. It'll instead continue to curate or not curate and maintain an active stake in the future of inflation, making the curation rewards pool more competitive and taking a larger and larger share of it.
These are just examples, it could simply also just vote on hbdstabilizer or non-curation while growing its share in curation rewards over time.
Anyway, would appreciate some thoughts on these couple ideas, and maybe someone who'd be interested in working on them as I think I may have overstayed my welcome towards other devs to do things for free or swamping them with ideas. :P
