I remember back in the day when Google came out with Google+ I think it was called. It was honestly a far superior product, but so many people were already entrenched in Facebook that it never quite took off. They eventually ended up shuttering it which was a shame.
Yeah, I got on for a bit, but it ended up being too unwieldy and so few were using it exclusively - most were still on Facebook. At the time, I was just interested in meeting up with people IRL and FB was good for organising it. I don't think I have logged in for a handful of years.
The main thing I use Facebook for now is special interest groups. Those have hundreds of thousands of people with lots of good information. I liked how Google+ allowed you to have separate containers for your friends. Like work friends, family, close friends, etc.
