I find these two claims together a bit odd. "It is well known, that social buttons effect your site’s overall loading time." "Like Button is loaded asynchronously and does not slow down your website." All popular services I know of also load their social buttons asynchronously, and just because it doesn't block rendering, doesn't mean it doesn't slow things down.
