I'd appreciate Kynn, and your point would be more effective if your posts
did not contain so many personal attacks but concentrated on the issues
themselves, I feel complaining without offering anything constructive
about my inability in written English is particularly unfair

That's how the statistics for current UA's is used though by authors, and
it will be even more so with CC/PP - there have been many questions
asking for statistics on the number of disabled users to create Business
cases, if CC/PP shows <1% of a speech browser (say) then there's no
business case for supporting them, if it's an unknown, or we can create a
more unified approach, then there is a business case.

Content negotiation based on UA strings works atrociously, if you'd spent
a few minutes reading comp.lang.javascript you'd see hundreds of
situations where using the UA string creates failures - and that's when
the author believes there is only a IE/NN duopoly and it still fails in
one of those, let alone the 23+ different javascript supporting browsers
I know of (+all their different versions of course.)

Perhaps that explains why I get broken CSS then - What does it give
Snufkin? - how can I find out, and get it corrected so I have valid CSS?
Do you have a resource, or an email address where I can address this?

You made a defence that P3P would allow a user to protect themselves from
increased hacking risk (only part of the defence, and I agreed with the
whole.)   This is of course silly as anyone who was thinking of using the
CC/PP information to make hacking simpler would also lie about their P3P

CPU, Bluetooth etc.  Screen Size (because it says nothing about how large
my fonts are, or how large my viewport is). Consider Figure 3-9 in <URL:
http://www.w3.org/TR/CCPP-struct-vocab/ > it says nothing of use about
accessibility or the user, it talks about the User Agent (which you've
just argued against due to the "table of capalities" needed.) and then it
talks about platforms - again this prevents new platforms from arriving -
nowhere does it do anything about capabilities - so is the current
proposal useless and against what you want of CC/PP if so where are the
reasonable proposals that I might be able to support. The current
proposals are nothing but a rejigging of the failed UA string.

> And CC/PP likewise will only send what someone chooses to send.

In one paragraph users don't do anything for it to work - and now they
get full control - it's difficult to argue both ways.
