Well, I need them so that my users don't have to wade through 300+ (and
at some point within a year, 3000+ ?) unclassified items to find the
kinds of news that they want.

I agree that none of the schemes that we have discussed would end up
catching just the commercials that you care about in the commercial
archive. I am planning to handle this at two levels. First comes
classification
so the user can choose at a gross level the interesting channels. Then,
within that will be some sort of text-based scanning of the headlines
to identify interesting articles and highlight them or put them off
on the side for safekeeping (I have some very big plans here). So
I would handle this by letting you subscribe to the commercial-archive
channel and then filtering it for some keywords that you would
enter. Not yet perfect but a step in the right direction.

What are the proposed uses of classification? I think a centralised, agreed
upon scheme may be barking up the wrong tree a bit.

Think of it this way; users will select the *kinds* of content they want by
selecting appropriate channels. Where classification may come in handy is in
categorising the content within the channel's domain. As such, IMHO it will
be unworkable to use any third-party scheme, whether it's Yahoo, DMoz, Dewey
Decimal or anything else; nothing will be specific or relevant.

To give an example:

One of the channels I would like to be able to subscribe to in a perfect
world is for the site:
http://www.commercial-archive.com/
This site publishes commercials online (fantastic use of bandwidth, I know).
The theoretical channel here would inform me of new commercials as they make
them available. Now, consider:
1) is there any external, non-domain specific classification scheme that
will add value to this resource? On the face of it, I'd say no.
2) even if there were, what value would it give? If the new Volkswagen
commercial is correctly categorised (once again, whether in Dewey or Yahoo),
will anyone get any real use out of this?

This example can (and should) be repeated on a multitude of sites.
Throughout all of my test cases, the site itself is usually the best source
of classification.

How would it be used? I can visualise a user agent that, when you download a
new channel, also fetches the classification specs for that site, and
presents you with a list of classifications that you can have
highlighted/ignored/treated special in some way.

Thoughts?
