It is indeed an interesting experiment to mix money with social, and as you've pointed out, there are several potential implications and challenges.

Introducing money into social interactions might indeed change the way people interact with each other, as well as the type of content produced. A primary concern is that users may prioritize earning money over genuine interactions and content sharing. People might feel compelled to create content that they believe will yield more financial rewards rather than expressing their true thoughts and ideas. This could lead to a less authentic online experience.

Moreover, the introduction of money could exacerbate existing social comparisons and envy. While comparisons are common in social media environments, the addition of a monetary aspect could heighten these feelings and potentially lead to negative consequences for mental health and well-being.

Misalignment of goals is another issue that could arise, as you mentioned with the example of Steemit. Users might focus more on earning money than on creating and sharing valuable content. The risk is that the quality of content might decline, leading to a less engaging and meaningful platform.

Despite these potential drawbacks, there might be some benefits to introducing money into social interactions. For instance, content creators could be financially rewarded for their work, which might incentivize higher-quality content. Additionally, integrating money into social media could lead to new and innovative ways for users to support their favorite creators and causes.

To better understand the psychology of money in social interactions, it might be helpful to look at research on the effects of financial incentives on motivation and behavior. Studies have shown that financial incentives can sometimes have a positive impact on performance, but they can also lead to a decrease in intrinsic motivation and even hinder creativity. As with many things, the effects of money in social interactions will likely depend on the specific context and the way it is implemented.

In conclusion, the intersection of money and social interactions is a complex and fascinating area to explore. While there are potential downsides to consider, there might also be opportunities for growth and innovation. Careful consideration of the psychological implications and a commitment to learning from the successes and failures of similar experiments will be crucial in ensuring the best possible outcomes.
