Note: Though I work on Chrome, I'm not on the UI team, so this is really just my personal opinion. I don't have much say in these areas.

Hastebin should change their shortcut keys to something that isn't already in use by the platform.

Overriding the established meanings of Ctrl+N and Ctrl+S is rude to users who rely on them.

This is no different than a Mac application (for example) implementing special behavior in cmd+tab or cmd+~. You'd be confused.
