not rocket-science, but something handy for debugging/developing web apps, use this to pretty print and validate the JSON responses

$ echo '{"json":"obj"}' | python -m simplejson.tool
{
    "json": "obj"
}

or

$ lynx -source "http://ws.geonames.org/weatherJSON?north=44.1&south=-9.9&east=-22.4&west=55.2"|python -m simplejson.tool
