The article is appealing. I think it can become better by using several arguments in case privacy does not resonate with a reader (e.g. financially exploiting personal information, building stronger social relations, how other countries use facebook alternatively), and listing viable middle-ground solutions (using aliases on facebook).

Example Solutions

1.Dont use your real name
