extemes and means of social media

During my presentation someone asked me what my opinion of the extremes and means of what a virtuous "Facebooker," although there are multiple extremes, I think that there are many that have to do with each other.  One way to judge a Facebook user is by how much time a person spends, the extremes are a person who spends all his time on social media and a person who never uses social media.  It is better to never use social media that to always be on it.  The second way to judge a Facebook user is how they use it.  The people who use it for only work and there are people who only use it solely for pleasure. A third way to judge is by how people interact with each other.  There are "Trolls," people who do not take anything seriously, who go around grinding everyone's gears and annoying them to get a laugh. And the other side, the side that the trolls pick on the most, that takes things too seriously.
I think a good way to determine the extremes is to be able to combine all of these extremes together to form two major extremes.
