Gnashups

Dharmesh from On Startups throws some water on the trend of companies being built using mashups of services from Google / Yahoo:

From Wikipedia: A mashup is a website or web application that seamlessly combines content from more than one source into an integrated experience. From Dharmesh Shah: A gnashup is a mashup that eventually causes gnashing of teeth because the developer thought she was building a viable business, when in fact, she was really conducting a controlled experiment for the benefit of Google and others.

He previously talked about why building a business where the business model is Google Ad Words probably is not realistic.
