You might already be familiar with Yahoo Pipes (a fabulous and completely underused tool). You might also be familiar with PostRank. But I never actually thought about combining the two services … clever.
At SXSW there was this presentation combining Yahoo Pipes and Postrank for filtering super power. Enjoy.

While there are some simple ways to make better use of your RSS reader to manage information overload, the real magic is in filtering. My favorite filtering tool is Yahoo Pipes, which lets me filter an RSS feed using various criteria: URL, author, date, content and more. Some examples of filtered feeds in my reader right now include industry analyst blogs filtered to only find posts about online community; searches across social websites where my projects are mentioned; and my some blogs filtered for just the best posts using PostRank.
