Interesting read. I agree with much and disagree with some.

Regarding "porn", I think you are just off base. You can read my detailed thoughts on the subject here: https://steemit.com/steem/@sean-king/thoughts-on-women-oppression-and-porn. However, in the meantime, I would challenge a couple of your contentions here. First, with coming filtering, nobody who doesn't want to see "porn" on Steemit will be forced to endure it, or at least they rarely will. NSFW content will be "opt in" or "opt out"--as easy as clicking a button. People who don't tag their content appropriately will be downvoted to oblivion.

Second, the idea that serious people with serious money will steer clear of anything involving porn is just misguided--twitter is filled with porn for those who look for it. Tumblr is filled with porn for those who look for it. HBO and Showtime (and the cable networks that carry them) are filled with porn, or soft-core porn at least.

It's naive and unhelpful to think that porn won't be an important part of steems' growth, just as it has been for every new technology--from VCRs to DVDs to the Internet to Bitcoin to Virtual Reality, etc.
