Geocities was full of a lot of things. There were pages that were just ad farms, often with no meaningful content except a bunch of key words hidden in the background. But there were also plenty of clean and useful sites by people who wanted to share their passion with others.

The later all but ceases to exist. Even if you are sharing your passion, you are doing it on a social media platform that is using your content to drive your audience into seeing their ads. You are ad bait.

That's very different from the web of the turn of the century.
