Trails can build HP when you have less time, yourself, they have curators who do nothing but seek quality stuff for you. I've supported many'0 trails.
A little bit of math goes a long way. Appreciator, for example, votes at or around 8%. Qurator, about 43%. Whatever you set your vote at (50, 25, etc), will trail theirs by that percentage. Hope that wasn't confusing. By gauging a trails daily VP usage, you can gauge your own.
Plug your research into hive.vote and, 'tada!' Earn.
Hive.vote, huh? I feel like I’m already a step closer!
