Sure. We can say a lot of things about a lot of different sites. But we know this:
There is no monetization of content on Steemit. So what we post on a daily basis doesn't "add value" or "reduce/remove value" from the site. Any claim is completely subjective and the criteria would be arbitrary.
A site like Facebook does not earn its valuation because one user posts cat memes and another posts 20,000-word essays on the LTV. The content is pretty much irrelevant. That's not how valuations are made on social media.
