Read more blogs in less time?

Hi! I am a blog nut and use the heck out of Google Reader. I have my blogs organized by category, very neat and tidy. Unfortunately, I have A LOT of blogs in there now! Over 1200! I just can’t keep up any more. I was wondering if there was some app or site out there that might do a better job of aggregating the content, or maybe organizing the data for faster scanning? Google Reader is great, and very efficient… But it isn’t helping me feed my knowledge addiction adequately. Thoughts?
