MIT Technology Review reports that:

"In the last two years, Google estimates more than 50,000 mashups have been built on its maps to highlight information about gas prices, running routes, earthquakes, apartment vacancies, home prices and a wide range of other information.

Google is hoping to unite the information mishmash by encouraging mashup developers to package the creations into mini-applications called ''mapplets'' that will be posted under the ''My Maps'' section of Google's Web site.

Multiple mapplets can be laid over Google's map simultaneously, meaning a user theoretically could get a glimpse at where homes are being sold in a specific neighborhood while also analyzing the area's recent crime patterns."

Bring it on!
