For me, coming online in the late 1990s, I've never experienced as much "education density" as I did when learning HTML to build sites on Geocities. For those who didn't experience that, circa 1997, you could either upload files or write HTML in nothing more than a textfield. No highlighting, no WYSIWYG, no page builders. Just you and a blank canvas (if you were lucky you might use an editor like Homesite or HotDog)
