I find it quite interesting that blog post about such topic uses Google API JavaScript which can track you, and link to your Google account that you are reading it and mark that you are interested in such stuff.
Yes. It makes three requests to googleusercontent.com and one to fonts.googleapis.com.
It's interesting because the site has gone to some length to host jQuery, Bootstrap and other stuff you could see referenced in HTML source, but CSS file requires stuff from Google servers. So maybe they simply missed that one.
