Will mashups ever be mass market?

I don't believe that mashup's themselves will ever be "mass market" in themselves. This is not the same as saying that a mash-up can't be a great idea and potentially lead to addressing a niche market (even one that becomes ubiquitous), but at the point it is no longer really (IMHO) a "mashup" and has graduated in to the big-wide world of reliablity, scalablity and robustness.

I believe that mashups themselve can't be mass market because they are principally there to solve a single person's problem. I do think that that the infrastructre and tools to build mashups can, however, become mass market and creating enough pieces to be mashed is already getting there.
