I'm using this bit of code to display the number of users on a site. My customer is complaining it looks fake. Any suggestions?

    var visitors = 187584;
    var updateVisitors = function()
        {
            visitors++;

            var vs = visitors.toString(), 
                 i = Math.floor(vs.length / 3),
                 l = vs.length % 3;
            while (i-->0) if (!(l==0&&i==0))
                vs = vs.slice(0,i*3+l)
                   + ',' 
                   + vs.slice(i*3+l);
            $('#count').text(vs);
            setTimeout(updateVisitors, Math.random()*2000);
        };

    setTimeout(updateVisitors, Math.random()*2000);
