What does Google Hangouts do well? Super easy way to keep communication within the same window as email, but without clogging my inbox. I'm a big proponent for simplification where possible and this has been a great way to achieve that.
What does Google Hangouts not do well? Having multiple windows open can clutter the screen. This could have a different layout, maybe on the side like Keep or Calendar does.
What do you wish you had known about Google Hangouts before using? That it wouldn't be a permanent feature :(
Have you used a competitor to Google Hangouts? If so, how does it compare? Not recently.
