I think I've discovered my mutant superpower. I've long pondered this after we discovered honeyfield's ability, which is the power to speak to anyone, including extreme geeks (artisty/gamer/programmer), for extended periods of time; hers is a very useful power to have at Comic-Con.

My power, depending on your allegiances, either qualifies me as a superhero or supervillain. Without saying what my power is specifically, I will present evidence rendered in crude infovis.

MacWorld (data you have provided in comments, as well as macs at work not in my immediate vicinity):

Mac Office ('k' = me):

iLife (Macs that have had direct, frequent contact with me [metamanda, honeyfields, d, parakkum, ln m, pqbon]):

I think I'll make frequent trips to the Apple Store to see if I can focus my powers...
