Ok, so I alternate between here and FB. FB is a ministry for me, it keeps me busy.
I'm disabled and in a lot of pain right now, social media helps distract. I'd rather be riding my bike, visiting the elderly, or my grandchildren.
But I do think you raise some very important questions in the OP. If I was young and healthy, I don't know if I would spend much time on-line. Then again, 20 years ago, TV was the big addiction. Before that, it was people! Seriously, spending time with others is what people did on the phone or in person!
Those were the days! Lol
