That's a curious statement. While I don't have much interest in much of what Google does, Google Hangouts does certain things very well.Hangouts is horrible. Furthermore, Google half-asses things so they give up on projects midway through. Right now they have 5 or so different communication apps with no direction. Bottom line, you care more about Hangouts than Google does.
One thing that comes in handy are free calls over WiFi back to the USA when you are traveling abroad.
