First of all, this would have to be better than Google Reader for people to use it, and even then, people probably wouldn't switch. Secondly, Google already shows users the data about how often they read articles from each feed. If it turns out that ordering feeds by priority is a good interface idea (which I think it is if you have search as well), then all Google has to do is write a few lines of code and the feeds will be ordered automatically using the read frequency data. The way you explain the idea makes it sound novel, but to users, all they'll see is that you'll be able to reorder the feeds instead of putting it in alphabetical order. The data would be useful for bloggers, but it has to be appealing enough for end users to use as well, or there won't be any data in the first place.
