There's a new way to get thousands of local points of interest into your web maps: the CloudMade Data Market Place. There's a fee for using the data, but otherwise it's as easy as the standard CloudMade API (our CloudMade API profile). For a few hundred dollars per year, you can add any restaurant in the U.S., hospitals in the UK to your map, or one of about 80 datasets.
U.S. government agencies may be tossing down nearly a million dollars each to include the premier version of Google Maps on their sites. The payments aren't going directly to Google, but an Ohio service provider Onix Networking. Onix lists several options on Apps.gov, a marketplace for technology services and applications.
