One of the most important evaluation criteria of a publishing system, regardless of its type, is how it implements the basic operations of Create, Modify, Delete. This is a standard that we no longer question at the operating system level. However, when it comes to anything we put on the public network, these fundamentals should be given even greater consideration. Creating content is one thing. But editing or even completely deleting (without it still lingering somewhere) seems to be more of a luxury.
With centralized systems, one never knows if there might still be a copy somewhere. With decentralized systems, it seems even impossible. At least for now. However, this does not render this age-old principle obsolete.
The next big "system" would be a decentralized, uncensorable protocol that cleanly implements C-M-D (Create, Modify, Delete).
