Little known? You must be kidding. It has more than 1 Billion installations [0]. It's pre-installed on every Android Handset and is the designated successor to Google Talk, a once great XMPP chat service which had offered real xmpp federation until Google rebranded it to Hangouts. I really liked Google Talk back then, Hangouts gradually made it worse and worse. The hurdles to onboard new chat members are too big (you need a G Account, needed a Google Plus profile at some time). While the G Account is a given on Android phones, it's a big hurdle for adding iOS users. The process is buggy as well: After adding an account for a friend, we often had to wait 1-2 days to "find" the person on Hangouts and be able to add them to the group chat. On top of that, the app is slow slow slow (the browser chat as well). As a community moderator I had to deal with above issues constantly but we kept using Hangouts for years... despite its shortcomings. Ultimately though, we abandoned it and switched to Telegram. Much faster mobile Apps, super easy onboarding for new members and a great Browser client as well (plus the company is FOSS friendly, allows custom implementations). The Hangouts dev team even knows about its bad reputation and the product manager even acknowledged that at some time [0]: "P.S. Unlike what the /r/Android subreddit says, the Hangouts team does come to work every morning trying to make it better :)" [0]: https://plus.google.com/+MayurKamat/posts/T1FNqgAWzgE https://plus.google.com/+MayurKamat/posts/T1FNqgAWzgE
