What people not using social media don't seem to understand (and actually people using them often don't understand as well) is that you do not have to give out personal details.
I mean previously I used an RSS reader a bit to read the news articles of my favorite news pages. Now I just follow them on facebook.
You can have an account on facebook and just follow your favorite podcasts, in my case
-Insert Moin
-Spieleveteranen
-Retrokompott
-Stay Forever
And you can also follow your favorite game studios, or ones which seem to make interesting games, like I am following:
-Bumblebee
-Crafty Studios
-Stellaris
-Might and Magic
-Master of Orion
-Bards Tale
-Wasteland
-Avernum
-Expeditions Series
-Numatian Games
And many, many more.
So you could use Facebook for example as great ressource page without having a single "friend". And even when having friends it's up to you which info you publish there and which you don't.
So all in all, reading facebook isn't that much different than reading RPGWatch news and writing a comment to the one or another article.
