Google is making refinements to its Maps area of its website, allowing users to move the location indicators brought up by address searches. The Washington Post reports that Google account-holders will be able to do Wikipedia-style edits to inaccurate address information. In order to prevent malicious users from playing with the green address markers, several limitations will be imposed. Google will only allow a move of 200 yards without its approval, and users will not be allowed to move markers for essential services – such as police stations, hospitals, or schools – as well as any business that is registered with the company's Local Business Center.
