As you can see I have enabled Facebook integration so you can like and share threads.
It does add to page load times, but you can block Facebook and Google Analytics with either Blur or Disconnect browser extensions in Chrome and Firefox...

Disconnect Me
Firefox: https://addons.mozilla.org/en-US/fir...on/disconnect/
Chrome: https://chrome.google.com/webstore/d...fhpjdfeo?hl=en

Blur
Firefox: https://addons.mozilla.org/en-GB/fir...onottrackplus/
Chrome: https://chrome.google.com/webstore/d...baefekcd?hl=en

These are well worth installing anyway.
