I'm surprised by this, it isn't actually my experience.  But perhaps
the issue isn't that a majority of people use group chat, but that a
majority of people expect group chat to be available if they want to
use it. GChat, Facebook Chat and iMessage all have group chat
functionality and if one were to remove it, I'm not sure people would
be happy.
