I've been contacted by one of the co-chairs for this year's Cascadia IT Conference to ask if I'd add a link, and I'm happy to do so. This is the second year of the conference, and if last year's is anything to go by it should be another great time.
Unfortunately I won't be able to go, but if you're anywhere in the area next March I'd recommend it. And if anyone's interested, I have no financial interest in the conference, but I have met some of the organizers at past LISAs.
