Add Mavericks' Mail problematic integration with Gmail to that mix and what I had was useless filters, lots of important messages going to "the archive" without me ever knowing, and useless desktop notifications popping up for messages I didn't give a crap about. Pull requests mentioning me? Those would go to somewhere in the Archive. Completely random comments or commits on other projects I'm not working on? Yup, here, have a notification. Aaarggh!!!
Luckily I found a completely random rack that restored some sanity.
