Filtering RSS feeds

The other day I had the idea that being able to filter high-volume RSS feeds would be very useful. I started developing a solution, but tonight I realised I hadn't checked if anyone else had the same idea. Googled and, yes, many others had. Most of them provided simple keyword filters (inclusive) which is, frankly, crap when you put that function in context. Take, for example, MSDN Blogs which generates at least 100 posts per day (less on the weekend). This is the conglomerated feed of all MS tech blogs. To apply a keyword filter to this is useless, since the whole reason I read it is to keep up to date with the Microsoft world. Filtering by such a precise method will cause many interesting topics to go unseen. Same with something like slashdot. In other words, keyword filtering won't cut it with blog browsing.

Filters like date range, author, and tag work well these types of feeds because they are broad. And that's why I chose Feed Rinse because they provide the above, a nice interface, and tiered membership so if you're really serious about feed filtering you can pay for the privilege. Shame I didn't think of it first but at least I now have decent filtered feeds available and I barely had to lift a finger!
