First, Curacao is an island nation. Here's the wikipedia page.
However, when I hit geo.placemaker with the string "curacao" I get random city in Venezuela:
<place xmlns="http://wherein.yahooapis.com/v1/schema">
<woeId>383422</woeId>
<type>Town</type>
<name><![CDATA[Curazaito, Zulia, VE]]></name>
<centroid>
<latitude>10.3833</latitude>
<longitude>-71.3333</longitude>
</centroid>
</place>
Any idea why this might be happening?
