What Are the Best Social Media Sites?

We don't want to be staring at screens all day. So eventually, I do just want to reduce it down to to maybe one main backup social media site. But I'm not sure which one yet. Which one do we like the best? There's also the issue is some of these companies, will they survive? Some of them might go out of business and you know, bye bye. We can be very free on these backup channels. But we'll be more careful on the other channels.
