MoveMyData looks interesting:
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. Has anyone taken it for a testdrive?
PS I love the graphics on the site. A site that looks like that just *has* to be made by good people.
