What do you want to be able to customize?
igorhvr: Specifically, I would like to be able to filter out TechCrunch, CodingHorror and ArsTechnica articles. I never learn anything from them. (the comments, on the other hand, are sometimes interesting - but I still would rather not have anything from those sites appearing for me).More generally, the ability to filter out stuff I don't want to read about using a Regexp or a Scsh-style SRE in the Website URL would be great.
