Has there been a 'what is your exoshell' thread on LW yet? Would it be appropriate to have one? In the purest definition, mine is pretty small (a thousand lines of Perl or so), but if you include 'software you communicate with', which I think I do, it grows rather large, to include most of what's running on my server.
It has been claimed on this site that the fundamental question of rationality is "What do you believe, and why do you believe it?".
A good question it is, but I claim there is another of equal importance. I ask you, Less Wrong...
What are you doing?
And why are you doing it?
