Recently David Muir of EdCompBlog was looking for a way to use Twitter as a personal response systems (also known as audience response systems, electronic voting systems, clickers …). I’ve previously covered this technology in DIY: A wi-fi student response system, where I propose a solution for creating a voting system which uses wireless enabled devices, so my ears immediately pricked up when I read David’s problem. At the time David explored a number of solutions, including both free and fee paying, but was left scratching his head. Reading his post I immediately thought of Tony Hirst’s ‘Who’s Tweeting Our Hashtag?’ mashup where he uses Yahoo Pipes to find who’s been tweeting with a particular hashtag. This pipe calculates how many times an author tweets using a particular tag. Tony does an excellent job of explaining how the pipe is designed and modifying it for David required the smallest modification (changing the unique filter from item.author.uri to item.title).
