I think you just need to think about what you want, and think about what sources you read from. You say you have 68 sources in your feed, whereas I have ~100.

I think you just need to think about what you want, and think about what sources you read from. You say you have 68 sources in your feed, whereas I have ~100. Personally, I like Google Reader, but I don't use that to read my RSS (just manage it). Instead, I use Google/ig. I have several different categories setup and I don't necessarily read everything. One of the categories I have setup is mRead (short for mark as read) and I don't really read those articles (often), but I still subscribe incase I see a headline that screams my name, or if I want to use Google Reader to do a search within my subscriptions for something specific. If you have too much noise in your RSS versus signal, than you may want to double check what you've subscribed to and cut back, or add a "mRead" category of your own.
