You delegate and you get a daily upvote at 100% upvote weight. The more SP the account has, the more you get in return. I think it's quite fair for everyone involved.

As far as curation trail @canna-curate will try to upvote good content as in no shit, drivel or post written by hitting your keyboard with a tennis racket and specifically 420 content, so no politics, conspiracies or religion.
