WordCamp Vancouver is coming up on May 5. The organizers call it a developer focus, though I would probably amend that to be “professional” as there are also sessions about design, information architecture and content strategy, etc.
They recently lowered the ticket price to $40. They’ll be selling tickets for another 5 days, so if you’re a developer or WordPress professional in the Pacific Northwest (or would like to become one!), I highly recommend attending.
