The author of LibraryThing also has written MothBoard. Basically, you can have a free, web-based discussion board without registering.
The idea is to give your board a unique name which only people you want in the discussion will find. The discussion isn't intended to be a long lasting one so why would you need to register. I like the idea of short-lived things. It can be very useful when working on a project.
I'd like to see more time-sensitive blogs, something which could be created, posted to and then archived into a search engine for future reference. Perhaps even republished with the entries in chronological order so the flow of the blog could be investigated.
I bet internal blogs in this fashion would be very popular and helpful.
