Cristian wrote the post I was thinking about. There have been a few posts in the Italian blogosphere, sparked by an
article (in Italian) written by
Vittorio Zambardino,
a journalist, about aggregators and how they are presenting all posts
at the same level while newspaper and regular web sites are presenting
news according to their relevance.
Choice of sources is obviously what makes aggregators better today, but
this doesn't mean that there could not be an improvement in the way
news are presented. I like my "river of news" style of reading but I
had to separate sources in different groups to be able to handle them,
and I'm reading some groups (mostly bloggers) much more frequently than
others. A system which would allow me to mix again these sources but
still let me find interesting stuff easily while scrolling very long
web pages full of posts and articles would make me happy.
OPML reading lists
could be a very important part of this application, knowing who's
reading what in our trusted network is one of the keys. Other elements
to be weighted in the equation could probably be which links we click,
what do our friends write about and, of course, what do we write about
on our own blog.
