I loved the bare bones simplicity of Google Talk (Gchat?) as it appeared the sidebar of Gmail. Don’t recall why I turned it off. Seeing stories today that Google forcing the switch from Talk to Hangouts. I preferred the spartan UI of Talk but like Hangouts well enough for this.
I only use it with a handful of online buddies who don’t have an iOS device. 90% of my IM’ing happens Messages on my iPhone. But I’ve added Hangouts to the Gmail sidebar and will leave it for a bit.
