[23:07] I'm a curious person and like to take a look at the source when surfing websites every now and then. Did so on this site that I mentioned earlier. And I don't get why they would cram the code with loads of unneeded comments. Neither do I understand why they chose to load a font off another webserver, especially since I doubt that anyone can distinguish their "design choice" from any default monospace font on any given OS.
I generally don't trust requests to other servers. In my book, you allow the third party server to track your users whenever you embed external resources. Be it a YouTube video, a Facebook button, a fancy font or a shitload of unnecessary JavaScript libraries. As long as the other server is not entirely under your control - don't request external resources. Else you're guilty of allowing third parties to track your visitors.
