per revision voting

The current incarnation of wiki (using MediaWiki as a reference) has an abstract as well as technical deficiency.

Technically, it would be advantageous for users to be able to express Like/Dislike on any given new textual input on a given article. Without this, various contributions are unfairly forgotten and editors get little feedback on their use of time and energy. The end result is that the forces that would make for a thriving wiki-opolis flounder from opacity and natural “market forces” cannot come into play.

In the abstract, time shouldn’t exist. Keeping a historical timeline of each revision from the current standard page is not really that relevant as most content is time-neutral (in contrast, say, to an event scheduled for particular day). Instead, revisions that are well-liked, regardless of how long ago they were made, should stay on close-hand to the currently-accepted standard so that future editors can examine content that was strongly liked, but not integrated. Liken this to the cellular model of a nucleus (the standard), with various floating components that are close at hand depending on how useful they might be.

With regard to voting, there are in essence two primary ways I believe that users vote. Forget the scale of 1 to 5 or anything like that. A simple, incremental step up or down should suffice to express an interest along with a put-to-top/put-to-bottom to express an extreme interest (enough that it should stay on top) or extreme distaste (I don’t ever want to see this revision again).

The same thing goes for user-ranking.
