Facebook appears to be deliberately and systematically making it harder and harder for people to vary their self-presentations according to audience. I think that this broad tendency (if it continues and spreads) impoverishes public life. Certainly, the self that I present on this blog is very different from the self that I present in private life (I’m a lot more combative, for better or worse, in electronically mediated exchanges, than I am in person). It’s also very different from the self that I present on the political science blog that I contribute to. Both differ drastically from the self I present to my students. I don’t think I’m unique in this. And one of the things I like about the Internets is that I can present myself in different ways. This isn’t the result of a lack of integrity – you need to present different ‘selves’ if you want to engage in different kinds of dialogue.
