How long will this blog post last?

Whimsley has an intriguing blog post asking, simply, how long that post will last. What is the event that will exterminate that blog post, or this one? Is it just a lapsed subscription? A bankruptcy? Perhaps it will be a transition to a different technology, one which will leave this and so many other remnants of the digital world orphaned like mountains of 8-track cassettes.

Maybe the record of our condemned blog posts will endure a few centuries, or even through the millennium, on some big data-snarfing storage unit run by Google, universities, or a government. In any case, I found this a sobering thought on a darkening Tuesday afternoon. Comments? Maybe your thoughts can turn this into something worth saving.
