I won't be able to go to the Go talk tomorrow, but a project written in Go has been working very well for me: micro, a basic but rather good text editor — https://micro-editor.github.io/

What I like about micro:

· it uses standard CUA commands: Ctrl-S to save, Ctrl-Q to quit, Shift+movement to select, etc.
· it's terminal only
·… but you can use the mouse to move the cursor and select stuff *even over ssh*
· it's not bloody nano.

It's definitely a lot easier to get beginners using micro, as it works the way you'd expect.

cheers,
