I picked this up as a I dont want to run Chrome all the time on my machines. Although Google Hangouts (text chat) is supported, it sadly has a great deal of problems. From my understanding most of these are due to the way Google has surprisingly locked in certain functionality to only their official offerings.
Some examples:
Hangouts disconnects intermittently and requires a re-login (which can sometimes mean having to enter an application specific password again!) Restarting Flamingo reconnects without having to re-enter credentials. (good and bad?)
Hangouts disconnects, then reconnects automatically after a short time. This happens often, and the main issue is that you can miss conversations as this can happen while the app is offscreen. (Due to the next point)
There is no offline history sync like there is in official apps. If you are not logged in via Flamingo, and someone messages you, the only way to see that is to go to google+
Group chat is not supported.

All in all this makes for a very stressful user experience. Alas, there doesn’t appear to be a functional alternative outside of running Chrome, at least not on mac.
I hope that eventually some of these problems are addressed by Google or Flamingo developers.
