I believe there are services that allow one to make annotations on web pages. Perhaps they allow one to control the degree of sharing; that might go some of the way toward what Mr. Pennarun wants. An annotation might link into or out of a private wiki. I'd like something even more modest: a better place than Wikipedia to discuss software. Wikipedia policies just don't allow what I want for current software. E.g., look at the near uselessness of http://en.wikipedia.org/wiki/ReStructuredText http://en.wikipedia.org/wiki/ReStructuredText (if it's still there?) and then look at the discussion page and history to see all the useful content that's been deleted. Or just read the text next to the broom to feel the essential "Go away!" point of view. Is there a better wiki for software topics? Or are Google searches the best one could hope for?
