Interesting subjects in the blogoshere: data longevity. I agree with most of what Tantek says, and I've also read about Mark Pilgrim's latest writings. Most of what I do is also done in plain text and HTML. My bookmarks are more or less readable in ADR and easily exportable to HTML. I'm somewhat less interested in open hardware and open software, as long as the closed software produces open data, or is made to handle open data, I don't see a big problem.

There are some unresolved issues, like using online services that don't always allow export in a usable long-term format. Will my photo albums on my.opera.com still work in 5 years? 15 years? Yes, I've got lots of JPGs on my hard disk, what I really want to save is metadata about the selection I uploaded to share with others (which pics, comments, tagging).

Update: here's an example of the kind of problems online services can cause.
