A nice discussion of guaranteed message delivery semantics.  On the Erlang FAQ, of all places. 3:17:59 PM

Architectural Principles of the World Wide Web Appears to be the latest official statement along the lines of these comments by TBL. 3:12:34 PM

Sam Ruby asks whether the Google API violates idempotent-GET (which isn't the same thing as GET-must-not-have-side-effects, btw). I don't think this violates the rules.  Limitations on number of requests per user fall into the category of access controls.  The real resource for a search response is a list of matching results, but you can always get an exception response back from any request.  "You're over your quota" is a perfectly legitimate exception.  A standard HTTP response would be appropriate for this, perhaps 403. 1:14:03 PM

Joel is right on regarding Groove.  I've installed the preview edition, and it's very nice, but I can't see how it will really make my life better.  I can imagine that there might be some applications for the Groove platform that will be compelling.  But not if every user has to purchase a Groove license, then a license for the application.  Give the platform away for free, and charge royalties to application developers.  Give away the razor, and get revenue from third parties delivering compatible blades. 12:31:18 PM
