Developers have near infinite flexibility in what they put into a web page. They can change the layout, style, and content to create a bland Craigslist listing all the way to media rich-platforms like Youtube. Similarly, NFTs (through the tokenURI field) can be filled with data and links to other datasets. As we start to see developers and artists push the boundaries of this, we could see the same sort of flexibility and diversity in NFTs as we saw with web pages.
