I think you're using RSS very well (unlike what I used to do).
I like Apple products and use/write for them. I used to have MacRumors, 9to5mac, Cult of Mac, TUAW, The Apple Blog, TC, and a dozen more Apple-related feeds in my RSS (among other feeds). When there was a keynote or a new product announcement, all those websites would publish essentially the same thing over and over again, and I had to 'mark all as read'. I was using RSS wrong, and I'm glad I changed my bad habit. You're using it right and I'm sure you derive value from such a diverse collection of blogs!
