Here's what I always wonder. Most of us, in real life, have some sense of how social groups work. Some are better at it than others, some are more intuitive and some more conscious about it. But most of us know that if we, say, move to a new school, that these groups already exist, that their dynamics can be subtle, that the people in them have a history, and that the process of becoming part of one can be complicated. That just crashing the lunch table of the popular kids shouting "hey I'm new look at me" and throwing food is not usually the best strategy.
But, there are also always some kids who don't get it, who do exactly that, and who keep tagging along trying to be friends with people who are clearly not reacting positively to the idea. You know the kind of kid I mean. If you're watching from outside it's the saddest thing. If you're part of the group it's inexplicable and annoying.
Are the people who act that way on the Internet the same ones who act that way in real life? Or are they people who would do fine on the playground but don't understand that the dynamics online are exactly the same?
