Filtering the web with pipes.yahoo.com !

pipes.yahoo.com is alive! It tries to capture the philosophy very commonly
used in UNIX. pipe is used for using data of one process by some other
process. The same concept is used by yahoo Pipes -- it captures data on web
and provides an interface to use it for some other purpose.
Ever since I started using RSS feeds and recently Google Reader, I have been
overwhelmed by the amount of articles I get to read everyday. I would like
to read a much smaller number and wondered if there can be some filter. With
applications like pipe, filtering out the right news for me would become
easy! Although I am finding the interface of yahoo pipes not very intuitive
and fast, I hope it would solve some of my problems.
