Several tools are available that make it easier to create mashups. In this chapter, you explored the topic primarily by using a combination of two such tools, the Google Mashup Editor and Yahoo! Pipes, to create a mashup of geotagged Flickr photos and Google Maps. By creating this mashup in a number of manageable steps, you learned how to use the GME and incorporate Yahoo! Pipes. Moreover, by comparing the process used in this chapter to that used in the previous chapter, you get to see some of the advantages and ­trade-­offs involved in using mashup tools instead of ­general-­purpose web programming techniques.
