I made this a while ago and I guess I forgot about it.
The "OS Triforce"
I think it's kind of a neat representation. I would say that I'm about where the "e" is in "Linux User", but eventually I would like to make sure that I am somewhere in the middle triangle; it's perfectly fine to favor one OS more than the others, but you still have to accept and be ok with the others as well because nobody likes a fanboy.
