Pseudonyms and blogging
Just attended a really interesting panel at CFP 2006 on pseudonymity and blogging. A number of pseudonymous bloggers explained how they thought, why they "came out" and what happened subsequently. It is hard to stay pseudonymous - since other bloggers and technology strive to reveal those that shroud themselves in secrecy.
The take-away? That it is really hard to shield identity online. And that sometimes it may not even be worth the effort - better to hide oneself the way Nietzsche recommends: viel von sich selbst reden ist auch ein Weg sich zu verstecken.
