It mashes up Google Maps and Last.fm. It is useful because it tells me which bands are playing where so I do not have to go to each band's individual website to see if ones that I like are playing near me.

It mashes up Amazon eCommerce, eBay, and PriceRunner. It is useful because it tells me which website is selling the jewelry for which price (which one is cheaper, basically), so I do not have to go broke to have pretty things.

It mashes up Google Maps and Twitter. It is interesting because it shows cool bars, lounges, restaurants and clubs in the selected city with reviews about them. This way, I can start planning my 21st birthday party ^_^
