Their Wikimania slides have an interesting example, where a really problematic edit becomes gradually accepted simply from being there and other people editing the article but not fixing it.

- A "blame map". Some might prefer to call it a "credit map" to be more
polite. This is a data structure that lets you see who is responsible for what text. It can be updated on every edit. Having one stored in MediaWiki will enable all sorts of applications. Apparently it's old-hat, and not the subject of the present research, but it'll be great to have an implementation integrated with MediaWiki.
- A reputation metric. This is a predictor of how long a given user's
edits will stay in an article. It's novel, and it's the main topic of de Alfaro's research.
These two elements could be used independently in any way we choose.

- The value of the metric for individual users is obscured. The only
access to it is via the reputation-coloured article text. The annotated article text has no usernames attached, and the metric is not displayed on user pages or the like.
Can you clarify this for me. What is there to prevent me from checking a particular snippet of text that has been edited by only one person, and seeing that it is a specific hue, and basing my evaluation of his or her trust metric on that hue?
To be obscured would it not be necessary to only colour text that has been edited by multiple editors, thus limiting the usefulness?

It's time for us to think about how we want to use this technology. There are lots of possibilities beyond the precise design that de Alfaro proposes. Brainstorm away.
I have not yet changed back to thinking this may not be useful, but I think we need more information on the limitations and possible further improvements that can be made to it. Is there a fuller description of the underlying formula/algorithm somewhere?
