Does this work for anybody? I've plugged in 3 feeds, one was "unable to retrieve full-text content" (an sfgate.com feed) and the other two returned nothing at all in the preview (one a feed from kqed.org, the other an older wordpress blog).
I have a lot of experience with fetching and parsing feeds and pages, so I'm not trivializing the problem, just observing issues I'm seeing with this solution.
