Mashups, why all the fuss?

OK... someone please explain this to me.  What is so revolutionary about mashups?  According to Wikipedia a mashup is a web site or Web 2.0 (don't get me started) application that uses content from more than one source to create a completely new service.  I think I did that back in '98 when I integrated shipping data from UPS in an e-commerce application I was working on.

Granted API's available today are much easier to use and offer many more services, but just because you attach a cool buzzword to the concept does not make it new.

Oh yeah... ditto for AJAX :-)
