I'm hopeful for the guild systems and the curation trails. Ideally they get more weight behind them. e.g. https://steemit.com/steemit/@heymattsokol/your-votes-will-be-more-powerful-with-hard-fork-19-and-you-d-better-be-careful-with-them
Taxation may be too strong a word. Universal Basic Steem Power. :D
