Robert Scoble asks whether news aggregators should deal with feeds that aren't done properly?  Yes, it's the Postel's Law controversy again.  This is what I commented in reply:

I believe the spec should be strict and implementations should be liberal yet *visibly distinguish* good feeds from bad ones. Badly formed feeds should be displayed with 'broken' icons and posts should be displayed with a header or footer message clearly indicating that the feed data is bad. This should reduce or at least limit proliferation of bad feeds.

I call it the biased liberal approach.

FYI, I am neither liberal nor conservative.  I am also not confused.  What I am is confusing.  ;-p
