Some would argue the concept of Mashups has been around for years - and this ‘hype’ over Mashups is over the top. For years we have been getting data from other systems and combining data with the existing systems to produce a result.
Hype over Mashups because of the ease of end-users producing applications themselves through modern-day Mashup editors.
The concept of the end-user being able to easily ‘drag-drop’ and put together a hacked up application within minutes is new.
