I found WP quite a long time ago but only did I really start to read more of it, and as many others I found quirks, typos, errors and such and just couldn't keep my hands off it. So, now I kinda consider myself a semi-lurker, touching up stuff I come across. I haven't done any major work and I'm, to be honest, probably to lazy to do so. But, hey, someone has to proofread, right?
