Those types have already found this place. They just don't appear on trending or hot feeds.
There is more than enough people who would be happy simply if this forum were to provide an actual forum platform, and not just a market in votes. This would hold users attention by itself, and it would help a lot if the money making side of the site were deprecated, a lot. This focus goes directly against the very foundation of a social network. If this is just a blogging platform, then it will not be able to gain the level of adoption and contribution that it requires to really see it overtake ethereum, bitcoin, and the other cryptocurrencies that still have far more market capitalisation. If the objective is to replace facebook, then it needs to accommodate the social media function as well. If that means that the cost in the size of the database grows rapidly, then this will have to be accounted for.
But, quite frankly, the witness nodes in the centre at the top of the list, they earn enough money to accommodate such a large blockchain. If the growth rate did escalate this much, then it would indeed eat up a little more of the witnesses profits. I don't think anyone would honestly see that as a problem when the alternative is that this system fails to achieve the widespread adoption it seeks.
