A screenshot of the diagram of the Yahoo pipe.
Yahoo pipes lets non-developers mash-up the web.

Update: It really doesn’t seem to be working. We could use some help.
We’re experimenting with Yahoo Pipes to aggregate the RSS feeds for the following hashtags and accounts: #engageleb, #lebloggers, #lebelect, @ladeleb, #hibrme, lebanon+elections, #lebelections, #womencan. We’ve connected the Fetch Feed module with the Unique operator to reduce repetition by title. The results are here. If you happen to have experience with Yahoo Pipes and can guide us to a cleaner solution, please get in touch.
