I share your concern and I've actually been thinking a lot about this problem for the past few weeks. I've actually almost stopped posting over a month ago when I saw the first few boobs posts. I wanted a platform to discuss deep intellectual ideas.

However then I remembered history. The Internet was also mostly used for porn in its early days and that definitely disappointed the scientists who built it initially, yet it still took off.

Sexual desires is a part of human nature and we are quite repressed in this modern professional society where we cannot express our sexuality for most of the day because we are at work. That is not how humans evolved. We are naturally sexual creatures who bond with each other through sex, so naturally people will gravitate toward sex on an uncensored platform. If sexual content, especially ones from real people who you can connect with, are being upvoted, that means it is what society really desire the most. People crave intimacy and do not receive enough of it in out awkward super technologically advanced culture. Yet technology could be what will eventually fix this.

Steemit is a social experiment to show what is really valuable to society, and that is sex. As much as we pretend to be rational, we are irrational beings controlled by emotions. Only when we lose our ego can we fully realize this and achieve self actualization.

So even though I wasn't too happy that this platform "degenerated" from sophisticated posts about cryptocurrencies to pics of boobs, I'm learning to accept the results. Perhaps boobs add more value to society in a primal way that I'm not good at evaluation. So I should put aside my own ego and believe in the free market.
