For one, I welcome RSS (back) and say the more, the better. I much prefer to pull specific types of information at my own set intervals when I need them, instead of either having undifferentiated information pushed on me continuously like a blast from a fire hose, or having to reach out to manually check and filter many individual sources. The idea is to schedule my receipt and processing of the information, and then refine the stream itself as well as the intervals I use to view it and the total amount of time I spend on it.

I'm currently on the hunt for an RSS reader that has good filtering and sorting functionality, so I can (for instance) pull several feeds from only certain sources, but not see any posts/articles about terms A or B, yet see and sort any posts with term C by time, followed by either posts from source 1 with terms C and D, or posts from source 2 with terms E or F but not G, which would be sorted by relevance.

I know that's a complicated and probably poorly written explanation; but I'm imagining something like Apple Mail Rules for RSS.
