For faster websites, google recommend to load social plugins asynchronously.
Could you ask the developper to change a little the code to do it.
For facebook by example, only add
js.async=true;
before js.src = "//connect.facebook.net/fr_FR/all.js ..."
It is easy to do and be usefull for everyuser.
For other social widget, it is easy to find :wink:
