I'm not sure if LP rewards are the best way forward for a few reasons

not many use hive-engine to that extent where they know how LP works + the assumed risks of hive tied to it
along with deposit/withdrawal fees of the hive if they wanna get involved

also it'd be posh:hive in that case as zing isn't really connected to posh in the same ways along with us using the rewardpool to fund a lot of activities for POSH as it's a project that helps all hive stakeholders compared to zing that could technically do the same when it launches if successful outside of hive, but we haven't used posts/comments to fund that project which dilutes stakeholders as was needed for posh and we still rely on currently for liquidity stuff.

Maybe simple airdrops to posh holders depending on how much they hold & delegate to poshtoken with the extra hive would be enough for starters, or simply buying up and burning posh tokens with the profits generated by these different kind of projects that don't directly use the rewards pool to help fund the whole project.

It's kind of difficult to say all of these differences in text lol, but posh is a bit different compared to zing, even though it helped it early on get going and received a claimdrop in exchange, it wouldn't be fair to hive stakeholders to reward both posh and zing holders alike, basically.
