I have read before how the tone of receiving a text or message gives a similar amount seratonin (the love hormone) released into your body as when you receive a hug. We are set up to feel good about using our phones.

Very interesting, thanks for adding that.

often find myself grabbing my phone and swiping back and forth doing nothing, where I would have previously been on one of the two sites doing the same.

That is also very interesting, and more funny :) The automated habit of scrolling, expecting to do that behavior. Was there a feeling of something "lost"?
