var arTags = new Array();

jQuery.map( $("input[name='tags[]']") , function(obj,index)
{
   arTags .push($(obj).val());
});

var obj = {'new_tags'           : $("#interest").val() ,
           'allready_tags[]'  : arTags };

var post_data = jQuery.param(obj,true);

$.ajax({
      type :  'POST',
      url  :  'some_url',
      data :  post_data,
      dataType : "html",
      success: function(htmlResponse)
      {

      }
});
