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.
What's dangerous is that the fiddling feels productive, even when you're just learning/making useless gimmicky features.

>Are there any websites/screencasts that show such "masters" in action?
Purely for the sake of motivation.
I can get things done with Textmate but I feel I've hit a wall in what I can do with it. I've used emacs off and on for about 6 months now and I really want to take it on full time.
