PIPES and their uses?

Not for plumbing (although that’s a whole other story at the minute!!), but data pipes are always something that has interested me, my biggest issue I think is finding something that I would pipe together.

Before I go any further I should explain what pipes are:

1. You take data from a source (an RSS feed is normally best).
2. You do some parsing of that data and extract some useful bits, that you then that input into another feed source.
3. You then combine the two pieces of data to produce one RSS feed.

All this in the past would have been the domain of programmers, but it appears Yahoo Pipes have made this easy, not something I’ve ever played with but Nick Bradbury has created a brilliant example of a Yahoo Pipe.

My biggest issue probably still remains, what two things would I pipe together? I love the idea, but I’m not sure I can find anything to do with it!
