Why is it that we do not see many "Geek code blocks" anymore?
The last one I saw was attached to a Unix Guru's email sig.

I think they are a great way of confusing users/lamers.

You mean like this:

-----BEGIN GEEK CODE BLOCK-----
Version: 3.1
GCS d- s: a-- C+++ U P+ L+ !E W+++ N o--- K- w++++ M-- V? PS+ PE-- Y PGP+
t* 5+ X- R- tv+ b+ DI++ D++ G e h- r--- y?
------END GEEK CODE BLOCK------
