That's not quite it. For one, I have no control over what gets archived. My site with the photos would likely not get much traffic since it's only interesting to my family and friends. Also, it's a lot of content: currently around 4GB and growing. Instead, I'd like to be able to pre-pay for a managed server to run with a guarantee for the next say 100 years. If in that time, any of my descendants decide that what I have there is worthwhile they can renew it for another 100.
