The Internet is not a library. It's not an archive. You have no guarantee of content's continued existence -- less so that with respect to old piles of newspaper in your garage. This concerns me. Absent ensured storage and access (that can't e.g. be retroactively 404-ed via robots.txt), our very history is at risk. And with walled gardens like Facebook taking over more and more traffic, delivery, viewership... We may never know what happened. Even absent a deliberate, concerted plan to eliminate the evidence. Such privacy is fine, for private, personal conversations. Is it, for a paid advertising campaign reaching millions?
