Man, their website copy is cringe city:
"3 Availability Settings
Available means you’re free to chat if someone needs you.
Busy mode means you’re pretending to be busy so other users have to hit you up to see if you’re free to chat.
And away, well that obviously means you’re in the toilet."
This kind of cutsie stuff doesn't make me think they take the convergence of my private space and work space seriously.
