Jeff, you really made my day! This is so inspiring! I've often looked into "Trac" - just now because of changes in 3.8 that affected some plugins I did for my projects. I have to admit: I thought that working on core was reserved only for the "high priests and priestesses" of WordPress :-). I agree with a commenter above: I make it a 2014 resolution to look into core and see what I can contribute.
