Exactly. I encourage everyone to become a digital hoarder yourself. See a cool blog post? Assume it will be GONE in 5-10 years. So make a backup PDF copy, and throw it in dropbox. In 5-10 years if you re-encounter that page, and the internet archive is missing the page, you'll be delighted to find it in your own archive, and you can be the one who restores that information to the world.
