I am not very comfortable with Facebook and Twitter, and that's why I've kept myself away from such things.
I try to stay off Twitter.
I don't do Facebook, Twitter, I don't do any of the social media.
Twitter was actually the holdout in what has turned out to be my total purge of social media.
I avoid using Twitter and Facebook.
I stay off the Internet.
A 'social media fast' is a fast, I suppose like any other. In this case, you're simply giving up whether it be a device or a particular type of social media site. And I do this at least once weekly.
I don't look at Instagram. I don't have much to do with social media.
