Yeah. There's a wordpress.com blog I frequently go back to and reference and the author passed away in 2014. Thanks to it being hosted on wordpress.com it will stay up there for the foreseeable future. Had it been relying on monthly payments for hosting and yearly payments for the domain it would probably have been down already by the time I realized he was no longer with us (some three months after the fact). And at that point, not all content would've probably been in archive.org and thus lost forever. I also have a bunch of old blogs that I've just given up on at some point and now they're gone forever. Your last point is kind of what archive.org's Wayback Machine does. Haven't checked whether they have an API where you can submit URL's you publish* or if you'd have to submit new posts manually, but this could be a decent solution. It wouldn't cover non-tech people though. *) I just now quickly browsed through their API doc but couldn't find anything clear, other than uploading random files
