Finally got Yahoo! Pipes to do my bidding. (See sidebar.) After sleeping on my utter failure to extract the results I wanted, I realised I was using the wrong approach. I was mixing search results with RSS feeds and getting grumpy that I couldn't do things like 'sort by date' effectively.By changing to RSS inputs only, filtering them (not trivial but the debug helps you see where you're going wrong), and de-duping and sorting the end results, I have produced a 'river of news' style listing of all my various online material. It contains blogs from here, thinkerlog, IWR and SmallBizPod plus articles and columns from the main IWR publication.Obviously a totally egocentric first application for Pipes (sorry), and still not perfect, but getting the basics in place actually took only 30 minutes this morning. (Plus of course a fair bit of trial and error before I twigged how to do it properly.)Update a few hours later: I have added the publication date to the titles. That involved some head scratching, the results of which I've added to Dan York's blog post on the subject. I also discovered that VNU restricts the number of items in its feeds to ten, so my history is not what it appears to be. I'll twiddle over time. For now I'm heading off to another mashup maker. See you later.
