On yahoo pipes

Yahoo pipes had got incredible online media focus when it launched. In spite
of some initial hiccups with their bandwidth, they are working fine now.
People are playing with the pipes and a huge list is already
created.
I found this method great, but it can still be made better with better
filtering tools. I would love to have something which can take as input some
feed and search over those links to take out the really relevant one.
Currently, I take feed from digg which directs me to the digg site. I would
like to create a filter to take these as input and give me as feed the
actual site so that I can bypass the slow and heavy digg page. I hope such
improvements are in the pipeline - coming either from yahoo or its
competitors. By the way, after a long time I have seen something really good
coming out of Yahoo directly and not through an acquisition (I am not sure
if it is created by a team acquired by Yahoo).
