What’s Going On Here?
My name is Aaron Johnson and I created this blog both for me (mostly) and sometimes you. I've been saving mydeliciouspinboard.in links here and blogging since 2002. During the week (and at night and some weekends and well.. most of the time), I work in engineering at Jive Software. When I'm not working, I'm hanging out with my amazing wife, ourdinosaurStar Wars loving son and four chickens in the burbs outside of Portland, Oregon.See Also
