Okay, I'll shill my feed reader since it's an example of one that lets you organize feeds and doesn't present a firehose: https://addons.mozilla.org/en-US/firefox/addon/brook-feed-re...

It's only for Firefox though because I like my reader being integrated into my browser and Firefox was the only one that supported a sidebar at the time. Looks like Chrome supports sidebars to now. So mayhaps I'll update it.
