JQuery Socialist Plugin Not Working-Collection of common programming errors

I am using this plugin but I’m having no luck with it. http://plugins.in1.com/socialist/demo

I Am using a WampServer running the example code provided.

$(document).ready(function(){
    $('#content').socialist({
        networks: [
            {name:'linkedin',id:'buddy-media'},
            {name:'facebook',id:'in1dotcom'},
            {name:'twitter',id:'in1dotcom'}
           ],
        isotope:false,
        random:false,
        fields:['source','heading','text','date','image','followers','likes']
    });
});
