But today I was shown an article on "intuitive design". A longer article than I usually link, but well worth reading.
Wikis have changed a lot since I started using them. When I first hit the edit button, I got an obvious box of text with very little code. It was easy to see what change I needed to make, and how to make it.
Wikis now are much prettier, but also contain much more complicated markup. I seriously wonder if I would be where I am now if that initial "knowledge gap" had been wider.
