My anonymous friend has this to say about the Virtual Observatory:
"...makes me wonder how reliable [current personal] mashups will be over time. Will all of this still work reliably 1 year....or 5 years from now? What about when the original authors have left their respective organizations and technology continues to turn over? Which group will maintain this and ensure the integrity of the service? That's why I like the VO. It's legacy won't be VO standards, but rather cross organization cooperation and accountability."
Cross organization cooperation and accountability: this is really what the VAO should be.
