Five years ago as of this writing, I was jotting down some thoughts about wiki engines, prompted by doubt and disappointment:

It's 2017, and wiki engines haven't been a hot topic since at least the start of the decade. But wikis are still a thing, and the age of this technology is showing. I can't help but think, if one was to start coding a modern engine without all the baggage, what features would it need to look like something designed for (relatively) ordinary people from the 21st century?

(What about Markdown? It comes with too much controversy attached. And frankly it's just programmers who like it and use it, for the most part.)

Note, I'm not even talking about rich text editors or other fancy stuff. But when it comes to basic usability, there's simply no excuse nowadays.

Since then, my sites went through big changes, I have a new one, and all three contain at least one wiki. So what happened to all those ideas?

It's progress then, and all remaining problems seem tractable now. Better yet, old wiki engines are still maintained, new ones are joining the fray, and with movements like the small web or digital gardening they're of interest to people again. I'll take it.
