Use a laptop or tablet. This site is not very mobile friendly.
Depends on your definition of "mobile friendly".
Granted, you can display a lot more of the article and comments on a tablet or real computer, no argument. But I find I can read and enjoy FR threads just fine on my little iPhone SE -- the smallest form factor Apple makes, it's like 4.5" diagonal. It's rare that a thread has a huge long URL or oversized image that screws it up -- and those are the posters' fault, not the site's fault.
The so-called "mobile-friendly" forums and social media are horrible to read on a small mobile phone. They cram way too much crap onto the screen, never mind the ads and notifications and pop-ups and other noisy BS.
The last thing FR needs is to lose the simplicity of the current ad-free, quiet format.
If that's "not very mobile friendly", well, I'll take it. :-)
