content: I think I might be in the minority on this one but I really like hangouts, though the security is pitiful. I like being able to use it via the web (or even in gmail) as well as a lot of the feature sets. It's looking rather aged, but all in all I still like it. I really wish they would spend some actual time improving it, but I don't think even Google knows what the hell they want to do in the messaging world, they are changing crap daily.
