/*
    SPREAD jquery plugin for easy and nice Twitter & Facebook sharing + Directo email
    29.1.2010 //Antti

    USAGE
    1. load bit.ly javascript api
    2. load jquery
    3. load this plugin

    Then you are ready to rock:
    $("#your .selector").spread();

    or with options (see full list from script below):
    $("#your .selector").spread({email: false, twitterText: "Piippaa twitteriin", title: "My site is best", hashtags:"#mytag"});


    Since this is javascript-only, please hide your toggler-link as default and show it through javascript. Example below:

    HTML:
    <a href="#" id="share-toggler" style="display: none">Share this page</a>

    JS (jQuery):
    $("#share-toggler").show().spread();
