First off, great points Aaron. But I think you have to re-align your viewpoint a little.
I am left wondering how do we achieve the permanence of print on the Web?
I’m continually scratching my head over this. Since when has print been permanent? The only reason we have scrolls, manuscripts, antiquarian books is not because it was on paper (papyrus, parchment, etc.) but because some body found the content valuable or of interest. Think of the amount of print we don’t know even existed. What was the 310th thing printed on Gutenberg’s press? Anyone? Bueller?
For me this is the coup-de-gras of the #indieweb. That you, the creator, own the content and have the canonical version to keep. Your two points are completely valid (and worrisome) but at least now I have the chance to move hosting or, heaven forbid, self-host. With the magic of Google, Bing, and Yahoo there’s the chance that my content if of interest, can be found again even if my domain name and hosting went in a puff of smoke.
The same can’t be said for the millions of authors whose works are lost permanently because a publisher no longer wanted to print copies. Also the content we are generating now is easier, I feel, to transfer to new mediums than hand copying & illuminating by candlelight
I know this isn’t the main thrust of #indieweb, just my two cents, on my own blog, syndicated to Twitter and your blog.
