There have been times where the wayback machine has definitely saved data that otherwise would have gone poof, forever. Case in point: I was looking for some info on an old synthesizer -- there was a page written by a musician containing a treasure-trove of reverse-engineered info he'd compiled over the years including ZIP archives of undocumented system-exclusive messages and file/disk formats.. unbeknownst to him, the archives on his server had become corrupted about a year before I visited. This info was NOWHERE else on the net since he wrote it all himself, and he'd not backed the files up (yes, stupid on his part).Anyway, long story short, the wayback machine had archived his intact ZIP files, which I helpfully emailed to him and he repaired his site :). Yes, he should have backed up his site, but he didn't, and the knowledge would have been lost forever otherwise. If you're so against the internet archive, I sincerely hope you never write anything useful on your site so no one depends on it.
