Eve Segwick argues that modern literature depends in large part on a dichotomizing tension between what she calls universal v. minoritizing sexualities. I think a similar tension exists in social media cultures between legitimate and suspect notions of the self—the self v. selfie, if you will..
This (via Nathan Jurgenson) seems like a useful way to contextualize the pejorative overtones that tend to attach to selfie. If we regard selfie as a shorthand way to describe not just images you take of yourself but instead the “self in social media” — which is regarded as illegitimate, contrived, narcissistic, false, uncontrolled, viral, etc. — the ideological significance of pejorative selfie becomes clearer. A lot more on the disciplinary uses of “selfie” can be found at this excellent blog of Anne L. Burns.
