Communication is good, meet new people is also good. As humans we need social life, it's like a basic necessity. It's the 3rd degree in maslow pyramid!
Although that doesn't mean we have to share all of our life in a social plataform. In instagram for instance i like to share more personal content, and in linkedin it's much more professional. But one thing is certain we only post want we want to be seen !
Internet should exist to make peoples lifes easier.

I enjoyed reading your post! Thanks @cabernet
