The only difference is that the post would live on a blockchain instead of a company server.

If you are talking about all the surrounding infrastructure, then that has nothing to do with NFT's. An NFT provides exactly the same value as a forum post. Someone can build a service which scrapes my forum posts and uses that to put links on another website based on some ownership details, so you can look at your owned posts there. You could make a whole game with assets based on forum post data etc, sounds exciting right!

Edit: Oh I forgot the other big difference. NFT's are crypto and therefore people pay insane amounts of money for it! Nobody would pay money for a forum post, that is just silly, but slap crypto on a forum post and wow, now we are talking!

Could you elaborate what the poster was a mistaken on?

Well, owning an NFT is absolutely nothing like posting a link to a Google Maps view of a house on Hacker News. It’s hard to go into detail on why those things are not alike without having more information about where this misconception is coming from.

Minting an NFT is exactly like posting a forum post. It looks like this, even has the same interface. Then people can buy this forum post from you.
