Tone of voice in warning messages

I’ve noticed recently a much more friendly, informal tone in the error messages being used online.

“Proceed anyway” and “back to safety” from firefox…


Hotmail, junk mail…


┬áChrome, this might hurt…

The style of language being adopted in online messaging recently has become a lot more friendly, and less formal. The firefox and Chromes messages sound like a conversation that the user would have with his or herself before making a decision.

“I’m not sure. Let me check”

There is no ambiguity about the intended outcome if the user were to click on that button.
