trenchant.org - daily

Can someone please write a real RSS reader that has filtering already?

I'm mixing syntax here but I want:

author =~ m/scoble/ > /dev/null

(source==flickr && tag =~ m/concert/) > /dev/null

title =~ m/Top \d*/ | mail -s 'delicious made me puke' josh@deliciousness

(source==twitter && title =~ m/flight(.*)delay/) { twitter.unfullow $author }

description =~ m/facebook/ {source >> ~/.blacklist }

But seriously everyone, please stop ruining the internet in 2008.
