cybercrud
     
         /si:'ber-kruhd/ 1. (Coined by Ted Nelson) Obfuscatory
        tech-talk.  Verbiage with a high {MEGO} factor.  The computer
        equivalent of bureaucratese.
     
        2. Incomprehensible stuff embedded in e-mail.  First there
        were the "Received" headers that show how mail flows through
        systems, then MIME ({Multi-purpose Internet Mail Extensions})
        headers and part boundaries, and now huge blocks of {hex} for
        PEM ({Privacy Enhanced Mail}) or PGP ({Pretty Good Privacy})
        {digital signatures} and certificates of authenticity.  This
        stuff all has a purpose and good user interfaces should hide
        it, but all too often users are forced to wade through it.
