I just meant I appreciate it as resource for all kinds of information, and as an invaluable backup of the web.

The internet should be a repository of all human knowledge and culture; all information and media should (at least eventually) be free as part of the common heritage of mankind. Sites like Wikipedia and IA are a partial realization of this dream. They aren't perfect, for sure, but we need them, and we need more sites like them. I fear too many take these things for granted.
