69 - Among these are: transaction validation, proof of work mining, liquidity rewards, and reporting of misbehaving block producers.

68 - There are other forms of contribution that Steem recognizes and rewards using objective metrics.

67 - Steem chooses to reward those who contribute the most to the total promotion of a piece of content and rewards the voters proportional to the ultimate reward paid to the content creator.

66 - Some platforms, such as Slashdot, use meta-moderation^ as a way to rank and reward honest moderators.

65 - Voting can therefore be viewed as a crucial contribution and worthy of rewards on its own.

64 - Voting input from community members is critical for Steem to accurately allocate payments to contributors.

63 - This means that people are given a familiar and widely used interface and no longer face the cognitive, financial, and opportunity costs associated traditional micropayment and tipping platforms.

62 - Readers no longer have to decide whether or not they want to pay someone from their own pocket, instead they can vote content up or down and Steem will use their votes to determine individual rewards.

61 - Steem is designed to enable effective micropayments for all kinds of contribution by changing the economic equation.

60 - There have been several attempts to implement per-article micropayments from readers to authors, but none have become widespread.

59 - The abundance of free alternatives means that enforcing a 'paywall' will drive readers elsewhere.

58 - The value of most content is so low relative to the cognitive, financial, and opportunity costs associated with making a payment that few readers choose to tip.

57 - However, direct payment is inefficient and not really viable for content creation and curation.

56 - Since the free market is a proven system, it is tempting to try to create a free-market system where content consumers directly pay content producers.

55 - The free market supports many different currencies and money is simply a commodity that everyone finds easy to exchange.

54 - The market system rewards those who provide value to others and punishes those who consume more value than they produce.

53 - The free market can be viewed as a single community where everyone trades with one another and rewards are allocated by profit and loss.

52 - A proven system for evaluating and rewarding contributions is the free market.

51 - The challenge is creating a system capable of identifying what contributions are needed and their relative worth in a way that can scale to an unbounded number of people.

50 - Eventually the givers grow tired of supporting the takers and disengage from the community.
