I have pages like this with a lot of social buttons. A lot means more than 50 buttons because each posts on that page has its own buttons.
So maybe I'll make the page smaller, with less posts but this is not the main reason and not what I am looking for.
I want to know how can I make the buttons faster..
Use XFBML? Iframe? HTML5? How can I make all of them run from one script and not duplicate? Do you recommend loading the rest of the buttons just when the user scrolls down? Do you recommend using a service like AddThis or Sharrre? How can I make all my JS load asynchronously? Other tips?
