Hey, I've just read your comment. As you see it is possible to boost ones ego even on the steem blockhain.
In fact I understand your point, but want to mention that one has the possibility to follow his 'friends' only and read their posts in ones feed only. The main difference with Facebook would be the unidirectional link structure. On Facebook your posts are presented to your 'friends' and vice versa. Not so on Steemit, which is more similar to Twiiter with its 'followers' in this point.
