Same. On Google Docs it auto-corrects to an en-dash (–), which is annoying, but I find the double dash (--) more easy to spot and read on computer screens.
Also, cosmetically I don't really like how em-dashes are used without spacing (e.g. "this—then that" instead of "this — then that"). Feels like we're trying to import publishing styles from newspapers and books heavy on serif font to places where monospace and sans-serif is the norm and it doesn't quite fit well.
