web2.0 sites' target
should be to offer each visitor
a stream with all interesting content
(most interesting first)
they need to track (forever) what content
each visitor has already seen
they need to model visitor tastes/preferences
to anticipate content-ratings
matching visitors with similar tastes
discovering the dimensions of taste
identifying content-prototypes
that can quickly map visitor preferences
ideally recognising five ranks:
A B C D F
where Fs offend you
Ds turn you off
As you want to share
with an 'emulate' mode
when you find a visitor with similar tastes
that lets you zip thru their As and Bs
inheriting their ratings as default
.
