This is a bit off-topic, but spiritually related to the mission of datalibre.ca … MoveMyData.org. From the “about”:
Your content and data should be yours to manage and do with as you please. Your images, writing, tags, profile, blog entries, comments, testimonials, video, and music should be yours to download and move anyplace you want.
We will help ensure that no website ever holds your data hostage.
I have not played with it yet, but I love the idea.
