gistfile1.txt

//open dev console of browser
//paste jquery.min.js contents
//https://github.com/jquery/jquery/releases

//load entire page
var scroller = setInterval(function() { window.scrollTo(0,document.body.scrollHeight); }, 1000);

//stop scroller
clearInterval(scroller);

var searchregex = /previous repl|more comment|see more|more reply|more replies|[0-9]+ repl/i;

var filterfunc = function(i, e) {
  var txt = $(e).text();
  return searchregex.test(txt) && !/hide/i.test(txt);
};

//count "more"
$('#pagelet_timeline_main_column').find('a').filter(filterfunc).length


//count "see more"
$('#pagelet_timeline_main_column').find('a').filter(filterfunc).length


//load "more"
$('#pagelet_timeline_main_column').find('a').filter(filterfunc).each(function(i, e) { $(e.click()); });

//walk away
var moreloader = setInterval(function() {
  $('#pagelet_timeline_main_column').find('a').filter(function(i, e) { return searchregex.test($(e).text()); }).each(function(i, e) { $(e.click()); });
  }, 60000);
