I'm sure someone's thought of this, but a "wiki" edit feature where you could edit your comment for clarity, typos, yet anyone could look at the version chain would be great.
think the difference is its just the option of how it is displayed. IIRC the first RBF transaction isnt recorded to the blockchain, here typo & edit are on the blockchain.
Yeah, I think an "edit" op would link to the post it mods, like reply does. The UI could show last ver by default but with icon & nav arrows that let you page through the edit chain.
Furthermore, you *could* have edits use a diff more cmpct fmt. Basically just apply edits to previous content. Like insert this string at this pos, etc. Might allow longer posts too.
This is sort of like a "stream" protocol. Akin to UNIX terminal ESC codes. Could clear screen, move cursor, etc. Could be compact way of chaining content *besides* edit capability.
