You're right. Though I'd probably argue that a lot of people may be overly concerned with discoverability, follower counts, monitization, etc. You can blog/podcast/make videos/etc. as easily (or more so) as you could in the early 2000s. And you can always just link from Twitter or whatever. If you don't stress about maximizing your followers all the capabilities are still there.

But you're right that the bias has shifted, e.g. long twitter threads (with no real archivability) vs. a blog post.
