Facebook allows me to do both.

I can casually engage with friends and family and also join private groups that are of interest to me.

I guess that is what I hope SMTs and Communities bring.

I can look at pictures of my friends, write a serious OP-ED or Story and if I were an artist, (and I am not) I could also post my work of art.

Meanwhile meeting and engaging with interesting people around the world.

I hope at some point that becomes what Steem is about.
