The maps mashup landscape changed forever yesterday with Google's announcement of My Maps, a new service which allows non-programmers to easily create maps mashups. With tens of thousands of maps mashups out there already this of course quickly lead to a tremendous increase.
In October Google announced pricing for its popular Google Maps API. Though most sites won't hit the free limits, those with a lot of traffic may be scrambling for a solution. That was the case for a New York real estate service, which discovered their bill would be $200,000 - $300,000 per year.
