I have been a die-hard user of the old Google chat, primarily because it let me add non-Gmail users to chat with them through the GChat interface.
Unfortunately I've started seeing this banner:
Google Talk will be replaced with Hangouts on June 26, 2017.
Tip: If you like the look of Google Talk, try the "dense roster" setting in Hangouts.
It looks like I'm going to not be able to keep living in the glory days of 2008 chat anymore.
Is there a way to chat with non-Gmail users in the new Hangouts? I've not seen these conversations in my Android Hangouts, either, so I'm not really optimistic.
