I'm surprised your comment has been voted up, it hinges on the assumption that learning the intricacies of a programming tool, in this case an editor, prevents accomplishing anything else with you life.

There may be other people out there that use an editor, or an OS, to impress others; but from personal experience and those of friends, there are plenty of people that learn vi and Emacs because they needed to get things done.

The right tool for any job depends on the person. Someone familiar with the details of HTML and CSS would likely be better off not using a WYSIWYG editor, but for someone unaware of and uninterested in DOMs and stylesheets that editor would be great.
