It’s not Robbing Peter to Pay Paul; Mashup believes in Taking from Peters and giving a brand new product to Pauls kind of approach. In short, Mashup is a mixture of two or more 3rd party public APIs that results in a completely new product. Some people say that whenever an application is developed without involving any private API, it becomes Mashup.

Lots of developers have started creating Mashups with Microsoft, Google, eBay, Amazon, Flickr, Serena and Yahoo APIs. Even Mashup Editors are now available; it is a WYSIWYG editor that lets developers create their own Mashups within a friendly environment.

With thousands of Mashups, it is necessary to keep track of new additions. Mashup directories and dashboards have already started doing their job. So web developers and users may get their hands dirty with Mashups – an exciting Web 2.0 feature.
