These design articles are interesting but I wish more would provide examples of what you should do instead of just what you shouldn't.

Exactly. I've seen the GUI wget example held up as a bad example [1] before, but I've never seen anyone try to produce a "good" wget interface.

Well, who's the user?

ffmpeg is far more complex than wget, and has some seriously intimidating output for "--help", but it does the sensible thing of guessing intention from file extensions/suffixes. `ffmpeg foo.bar foo.quux` will just convert your file, silently.
