Correct if the site goes down due to going out of business, etc I agree with you that is not censorship at all.
Though distributing the data across the blockchain could potentially even help from those eventualities too... I hadn't even considered that upside as well.
Yeah, an encrypted one. But companies make lots of backups, and send them to like Iron Mountain. The blockchain would be huge for nothing.
True.
Multi-chain connectivity yeah, I would say to create chains or side chains for specific media-types: text, image, video, audio, whatever else.
You did create a new chain of thought for me though and potentially a big business opportunity if people wished to pursue it.
Disaster Recovery aka DR
Is a big buzzword and requirement for many businesses now.
The blockchain would be a very resilient method of implementing a lot of DR services.
Side chains would likely be the way to go... with other connectivity. For video requires more storage and bandwidth, but they likely would be not created near as fast as the text blocks.
So have the main block your text block, with links to needed side chains as appropriate. Then you could potentially adjust thru put requirements to match on a chain by chain basis.
