PGP is a freely available tool for reliable encryption and identity verification.
I have and use my public key
when I'm serious about the safety and security of my email.
It doesn't hurt. If you don't know what PGP is, I'd recommend you find out.

I'm also a Dvorak keyboard
user, though when computer hopping,
I always used to have the darnedest time remembering
where the alternative layouts lived. Here's the Macintosh layout,
binhexed, here's the Unix layout,
which needs to be given as an argument to xmodmap,
and here's the DOS/Windows EXE
which supposedly unpacks to give you everything you need for Wintel platforms.

Alumnus of Wesleyan University,
The New Group,
also Alpha Delta Phi,
a co-ed literary society.

Rather than even try to give the random links I hit a lot a context, I've both used the fantastic scripts at "C.R.A.Y.O.N."
to assemble my own Picayune,
as well as simply putting my own bookmarks
up. Sheer hubris to presume anyone else is interested in my tastes (for example, in my current list of .signatures),
I know, but heck, huge amounts of time and energy on the Web are devoted to self-referential claptrap anyhow. How can mine hurt?

And in the Totally Narcissistic category:
Hear me
hurtling from a bungee tower at Macworld,
if you want. It was fun. I can't say much more than that articulately, since you pretty much have to shut your brain almost completely off to make your legs take you off of a very high ledge.
