The paradox of the internet archive's existence is if all that data were easily searchable and integrated (i.e. if people really used it) they would not exist by way of no more money for bandwidth and by way of lawsuit hell. So they exist to share archived data, but if they share archived data they would not exist.
and so it is a wonderful magical resource, absolutely, but your "power user" level as well as "free time level" has to be such that you build your own internet archive search engine and google cache plugin alternative... and not share it with anyone for the above existential reasons
