Feedhub, a recommendation engine for RSS feeds, may be just what you need to start really taking control of your information sources. Are your feed reader "unread" items a bit higher than you like? Feedhub can analyze what you are reading now and pull interesting and relevant stories out of the 'net just for you. The more you use it, the better it gets at figuring out what it is you like. You can also point it toward your FriendFeed or Delicious accounts or your blog to teach it more about what you are interested in. Once Feedhub does the analyzing of your interests, you will start to get stories in your feed reader that are tailored for you. Once that happens, you can pretty much delete most of your other feeds and rely on Feedhub to keep you informed.
I haven't been using it for very long, but it seems to do a pretty good job of figuring out what sort of news/stories/blog posts I will like from my feeds and delivering them to me. I'll keep tweaking the stories it sends (by going to the Feedhub site and "voting" on the stories it suggests for me) to make it work even better, though! What I'd really like is for it to pull stories from *other* feeds to show me that match the kinds of stories I like, as well.
This tool is another possible way to take control of your information sources and manage your time efficiently - use it if you feel like you want more control over the amount of information that comes at your via your feed reader!
