You could use the node tiddlywiki which saves the tiddlers in separate files, you could also use the markdown plugin and the tiddlers are saved in seperate markdown files. Perhaps as service could do a git commit with each file change in the background, perhaps saving the browserstring and ip address with it. You could make a seperate page - for example Gitlab with the commit history.
