Trust: My guess is people will know how much to trust wikinews, and regard it accordingly.

The blogosphere: Absolutely. Blogs are the eye witness of accounts of news big and small. Well, mostly small, but a few big. Though I can’t see anyone being able to give a first hand account of a really terrific story and posting it to wikinews, when they could sell their story to the Daily Mail (or get a job there) instead.

Perishable: Now that’s really interesting. Wikipedia works well in part because people have time to get it right. And there’s another successful model: open source software – collaboration on something durable. News doesn’t pass the durability test. But there must be other candidates that are durable… how do fancy starting a wikiart project?
