Interesting discussion topic. I think it will definitely play a large role in the steemit ecosystem but I don't think sex will dominate the social network. I look to other social networks like Twitter and Reddit which have rampant NSFW content but don't appear to be overrun by it.

Maybe this will reveal if those corporate controlled entities have been holding back sexual content from dominating their networks this whole time and steemit won't have that same overlord stopping the titty flood to come. We'll find out soon enough.
