Fun! Nice work too. I'll jump on the bandwagon with a couple suggestions too. I think I would have written the Conference section more like this:

C+++ - I am Nat Torkington, Kevin Lenzo, Leon Brocard or Damian Conway
C++ - I have given talks/tutorials at TPC or YAPC
C+ - I have attended at least TPC or YAPC at least three times
C - I have attended TPC or YAPC at least once
C- - I have never attended TPC or YAPC, my company won't let me go
C-- - I have never attended TPC or YAPC, and I have no desire to ever do so
C! - I have won a prize at TPC or YAPC

I also have one small suggestion for Perl Mongers:

PM+++ - I founded and/or head a Perl Mongers group

(By the way, Perl Monks and Perl Mongers each list two different abbreviations: PM/WP for PerlMonks and MO/PM for PerlMongers. WP and MO are probably best.)
