I'm Premeditated Chaos, also known as PMC. On IRC I go by PMC_x. The accounts PMC, PMC_x, and Premedicated Chaos are my doppelgangers. I use this name exclusively on Wikipedia, so in the unlikely event that you come across another Premeditated Chaos elsewhere, it isn't me. I have been a Wikipedian since 2003, and an admin since 2004. I was active on-and-off for a number of years thereafter until returning in January 2017. In December 2017 I was elected to the Arbitration Committee for a two-year term, which ended in December 2019. I had the checkuser and oversight permissions as a result of being elected to ArbCom, but have since handed them back in.
Unlike many editors, I don't have a favorite topic that serves as a focus for my edits. Sometimes I update and reference articles based on books I'm reading, but quite often I've just found something that both interests and annoys me enough to want to look into it more. I am particularly fond of digging up hard-to-find scraps of information about obscure things. I have a habit of chasing topics down a rabbit hole - correcting an error here can lead me to another one there, which sometimes leads to rewrites or brand-new articles if I get really interested. This process of leapfrogging hyperfixations seems to have led me to an interest in the goddesses of Georgian mythology.
I am often found de-orphaning articles, particularly from the February 2009 category. I've recently developed an interest in trimming excessive plot summaries, which I find weirdly satisfying. I occasionally comment on deletion discussions, especially if they are at a stalemate. You can occasionally find me clearing CAT:CSD and CAT:PROD.
I'm quite fond of list articles, probably as a result of my de-orphaning efforts. I have created several new lists, and actively maintain several others. Despite what my article creation habits might indicate, I don't particularly care for or know much about beetles, plants, or algae, but they are frequently found as orphans and also happen to be very easy to de-orphan.
