Boy would Google love you for a case study! If you already use Reader, you’re on the right track, just stick with the tool you’ve got, you’ll probably be frustrated if you keep trying to find a suitable alternative. (Learning to read faster actually isn’t a bad idea either).
As far as better aggregation of the content you want, Google’s already working hard to do that for you. My tip to you if you love all that info overload, is to meld your Google search, Reader and Google plus together.
If you’re signed in to Google, you have lots of personalization options for your search, your Google news home page, Reader – and of course it’s all integrated with your Google plus account. While G+ isn’t the ‘facebook’ it wants to be, I actually like that aspect of it. Instead of just all my friends and family, I have people in my circles with similar interests who share great stuff (and the +1 mechanic carries throughout all the Google services you use for content). Top all that off with Google’s “Google plus your world” personalized search results you get while signed in, the engine will ‘learn’ what you like – but you have to use all those resources and participate.
For you, all those services Google worked so hard on are actually perfect.
You might even think about shooting Google an email with an interest in being a tester.
