"Likes" and reading narcissistic postings probably are not a good substitute for real human contact, and the more people become addicted to social media the less real human contact they are likely to seek. Of course companies like Facebook and Google (YouTube) purposely design their offerings to be addictive and as we know additions can be detrimental to one's mental and physical health.
