The event focuses on case studies that demonstrate successes (and failures) in Web applications and Internet architectures. This year, we're adding Hack Day on September 28th. The inaugural, 2010 conference (http://omniti.com/surge/2010) was a smashing success and we are currently accepting submissions for papers through April 3rd. You can find more information about topics online: http://omniti.com/surge/2011 2010 attendees compared Surge to the early days of Velocity, and our speakers received 3.5-4 out of 4 stars for quality of presentation and quality of content! Nearly 90% of first-year attendees are planning to come again in 2011.
