I want to expand on one of the points I just made. As I think about the
issue more, the more I see signings of posts as being more of a help to my
enemies (prosecutors, in this context) and less of a help to my friends.

Consider that signing an article is offering something of value. (Standard
point about identity being just another credential, or element in a
negotiation.)

In almost all casual conversations, such as what we see on these mailing
lists, signature checking is not really needed. Absent evidence that
widespread forgery is going on, who cares whether "Mark Grant" is _really_
Mark Grant (whatever that may mean, philosophically).

Of more importance to me lately, given developing events, is that my words
will come back to haunt me in this post-free-speech era, where conspiracy,
RICO, and "plotting" are apparently the real crimes being prosecuted.

I'm not saying that signatures are not a Good Thing. Indeed, if I ever get
a version of PGP or S/MIME adequately integrated with my OS and Eudora Pro,
I may (or may not) start auto-signing all e-mail. (Gulp.)

(Oh, please don't barrage me with suggestions. I had two helpful suggetions
for "Pegasus Mail," ignoring the fairly well-known fact that I'm a Mac
user, not a Windows/NT user, and other suggestions about other products.
Puh-leese.)

What I'm saying is that signatures may be handing prosecutors too powerful
a tool to prosecute unpopular speech. Something to think about.
