I've been doing some reading on reputation systems. (I don't know that we want or need a reputation system in the Jabber world, but I'm doing that reading as background to thinking through the question.) On the web we have things like XFN to specify meta-data about links, but those do not explicitly provide appraisals of reputation. How does reputation emerge? PageRank and similar systems represent a kind of reputation. When I link to a page or a person or any other resource, is there a way to more explicitly tag the fact that I think that resource is valuable? I don't see quite such a mechanism in the semi-official microformats list or in a quick survey of various blog posts on the subject (such as this one). How about rel-whuffie, folks?
