You could write an article on how the internet is actually more real and dangerous social environment than real life because, in accordance with the ‘who you are is what you do when you think no-one’s looking,’ everyone on the internet is given a mask of anonymity to hide behind.
It tends to give people the courage to bare themselves on the internet, and when you get too close to their exposed heart, they can get very angry, very fast, etc. etc.
About the Chan boards, (4chan in particular) and their mutating culture, about the racial prejudice and callous, brutal (and usually sexually so(misogyny, prevalently)) opinions that people feel free to air because of this anonymity.
How something that might be a spirited discussion between two or three people in real life becomes a flash-mob of posturing and back-biting on the internet, because the anonymity rule, coupled with open-air access to everyone who browses across the page, mean that people basically just hammer their personal opinions down in a post with little regard for intellectual debate or compromise, or really the feelings, or really without even regarding the humanity of the people they’re fighting against.
etc. etc. Plenty of other examples.
Oh, one more. The internet culture has actually affected real life, because on the internet, everyone, in anonymity, has apparently exposed their urge to steal, and since everyone has seen that practically everyone else has no qualms with theft, the internet has actually modified interaction in REAL LIFE because now people bring up piracy without being afraid that anyone will report them.
