the general challenge
for 'blog science'
is to present a surfer
with a content stream
that grows more and more relevant
as that surfer's tastes
become known
tastes in music
tastes in movies
tastes in books
tastes in poetry
tastes in pictures
tastes in politics
tastes in humor
evolving a set of substreams
for each surfer
for each of these domains
comparing all surfers' tastes
and offering substream-subscriptions
with adjustable rates of flow
(casting wider in dry times
filtering the best during floods)
.
