To build a folly is essentially to do something a second time, something at an inopportune moment. That something is always the memory of something forgotten, about which we can paradoxically say "There it is again."
Follies were misunderstood, purposeless constructions. They were often only small, extravagant gestures in a garden, easily whisking off the imagination to distant lands, a sort of time capsule built to awaken the memory and induce surprise in passers-by. They marked locations, organized secondary paths in a park, or simply predicted the arrival of better times—a demarcation, a sacred spot, a mysterious trail, a hill whose tragic rocky nature begged for a tower, a party, or the arrival of summer.
“It is demonstrably true that things cannot be other than as they are. For, everything having been made for a purpose, everything is necessarily for the best purpose.” — Professor Pangloss
We didn't have Google in the early days. Other search engines like Lycos, Excite and Northern Lights did exist but were nowhere near as efficient as modern search engines. Finding something you were interested in was not as simple as typing a few words and getting to that information in one click.
No, the web was much more of an adventure. It was a place that you wandered to discover new areas, like exploring the vast open seas. A new virtual space that lead to all kinds of strange, interesting, exciting places. This is what the web was like, at least, in our collective imagination.
Google has become the de facto gatekeeper of the web, an arbiter of what is useful and what should get visibility. Except, most websites that appear on the first page, the links that you are most likely to click on—less than 1% of searchers click on something in the second page—are designed to be there by optimising for Google's algorithms. One consequence of this is that most of the websites that people get to "organically" are created by professionals and marketers who "position" themselves on those keywords. This means that the smaller, amateur web gets hidden in the shadows of web professionals who design around specific keywords and audiences.
It is worth remembering a website does not have to be a product; it can also be art. The web is also a creative and cultural space that need not confine itself to the conventions defined by commercial product design and marketing.
