Why TCM is wrong about PICS being wrong:
PICS is the wrong approach becuase it oversimplifies the ratings of content, because it places the ratings made by the author in the payload itself, and because third-party ratings systems are cut out of the loop (effectively).
bzzzzzzt. please read about it. there are multiple protocols. some of them allow third-party rating services. some of them support ratings within pages. the standard is neutral.
One computerish way to think of this is that the "binding" is too early. At the time of distribution, say, I mark my work something with some PICS label, based upon my best understanding of the PICS labels, ratings, agencies, and laws. But once set, the "binding" has been made. Later reviews or reviews by other entities cannot affect the binding, at least not for this distributed instance.
you have a good point, but PICS is about letting the net decide. it supports both self-rated and third-party ratings. we will see whether one eclipses the other in the long term. personally I suspect both will coexist.
And of course it is quite likely that things important to others in their ratings are not as important to me. I might even ignore certain points, not even seeing the need to point out things in the work. This is inevitable, as there is no uniform view of truth, no uniform set of values and priorities, and no hope there ever can be such a monistic view.
this is a ridiculous misunderstanding of the rating system concept. the PICS standard expressly supports diversity by letting a thousand rating services bloom, to borrow a phrase from your own book. some rating services may claim to be canonical, but you don't have to believe them. there will be competition of rating services for a long time into the future. this has already happened with all the filtering software out there. also consider the new Firefly system that doesn't actually have fixed ratings on objects, but in which ratings are determined dynamically based on your own personal ratings of pages. Consider
the recent example of AOL's lists of banned words, even words in "harmless situations" (e.g, the example someone cited of "tits" being banned, despite being the name of a bird...would an animal-lovers Web page or posting with "Tits and Asses!!!" prominently in the title be PICS labelled as obscene? Some would surely think so.).
this would be an example of the most rudimentary and simplistic filtering or rating service, which of course the market would generally ignore in favor of more sophisticated alternative schemes.
A much better solution is to let the unique ID block of an article--the Usenet article ID, or some hash of the headers, whatever--be a pointer that other ratings servies could then use to provide for their customers or clients as a filtering mechanism. This would allow as many ratings services to exist as clients would be willing to support.
that's exactly what PICS is about when you read about it more deeply.
More importantly, the "payload" does not carry some particular set of fairly-arbitrary PICS evluations. Binding by the censors instead of by the originator, which is as it should be.
PICS supports both, as it was expressly designed to. what Timmy is repeatedly failing to comprehend despite much evidence staring him in the face is that ratings services are going to be a very significant new information industry, if they haven't already become one. there are now many different filtering packages out there and the market is large for them, as has been proven by *existing* sales. this industry will grow. yahoo and many other indexing services are in fact implicitly rating systems, because they utilize editorial discrimination in deciding who to include and who to exclude. they just don't say, "this is rated yahoo approved" overtly. (timmy is also upset that a massive new industry is growing without his personal approval or anticipation. I will amuse myself by counting the days until he does a flip in position and begins to advocate rating system's efficacy while pretending his position was never otherwise) let a thousand rating systems bloom. PICS is about finding good content as much as rejecting uninteresting content.
