Not only did they quickly and easily learn how to write straight html code in a non-visual editor, but I also taught them how to interactively log in and manage the pico editor, etc.
These successes were not due to my skills as a teacher - they were due to the relatively simple skillset involved and the ability for normal people to learn something like this. These people were not geniuses. They did just fine. One of them went on to work professionally as a webmaster.
There is no reason to dumb-down web development - it is already as easy as it needs to be.
