I am Aegith. I'm also sometimes Kerin.
My pet peeve is low-quality writing. Most of my edits involve improving readability in poorly-written articles.
I've also a certain affinity for odd, obscure information (for example, my addition of the Play it Loud! entry in the Game Boy article. I don't think more than six people ever owned a Play it Loud! system.) I'm really not adding much new information to Wikipedia; I leave that to people much better at it than me.
That said if you see something that I got wrong, please tell me. I'm not going to be offended, and you'll keep me from looking like an idiot again in the future.
