Mashup Feed
"ProgrammableWeb’s ‘mashup-only’ site is live:
What is it? As the name implies it’s a site, a very small one-page site for now, that is only about mashups: recent mashups, popular mashups, mashup tag clouds, and some other miscellaneous stats about mashups"
Includes pointers to apps mashed using Virtual Earth, MapPoint and MSN Messenger APIs .
