I think it also makes a difference if you work with people across different timezones or not. Regular chatter might be good enough to communicate between people in roughly the same timezone. However, If I send an unclear chat (or email) to a colleague who's starting her day when mine has already ended, she can't act on my message and we'll have to waste another day clearing up that miscommunication.
