However, because of the nature of FB, it makes relationships less personal/authentic, as we try to show off our "best self" to others, rather than our real selves. The tool itself encourages this, so instead of adapting to it, for some people it's best to not use it.
It's like eating at a fast food restaurant. Yes, you can adapt to it and order the salads, and healthy dishes.. But noone's forcing you to go there, you can just not go to them in the first place.
