if I remember correctly, anything below $0.02 is deemed dust and is never paid out
2 cents after curation so it is a bit over 2 cents right now.
If this assessment is correct, and I want to keep giving meaningful up votes to comments on my post, even if STEEM drops further, it seems I might need to consolidate my two accounts back into one.
The main point of this curve is to discourage micro-spam, which is a large portion of the crap created on the platform. It is also to discourage larger stakeholders from breaking their stake into smaller accounts and hiding spam.
While you do bring up a good use case where this hurts the user experience, I suspect this situation is far less frequent than current micro-spam abuse. It's also something you can solve by consolidating your accounts, it's hard to expect the blockchain to bend around your desires and wishes, we have to look at what is good for the community at large and the sustainability of the platform. Right now micro-spam and abuse are plaguing the platform and retarding the price, your ability to reward commenters to your posts is not.
Does the cutoff have to be there?
Could the math carry to the 6th decimal and round down there?
I think abandoning a lineair reward curve (either with the EIP n(n+s)/(n+2s) curve or, for example, my proposal of an n(s^log(n)) curve), there shouldn't actually be any remaining justification for any dust level cutoff. If the curve does what it is claimed it does, the cutoff serves zero remaining function AFAICS.
I'd be some richer if the math was done to the 6th decimal.
Guess I'll add that to the list.
I hope it doesnt take 2+ years to fix hf21's debacle.
