Tom,
First, thanks for PHP snippet. Make me laugh 🙂 “complaining about the optimization of a file they serve”.
When I use @font-face rule, that suggestion goes away. I read pros and cons about @font-face but don’t get solid solution. It’s not like reading a debate. What’s your though on using @font-face? I rather like to go with your opinion.
Aside Google, testing my website (several times) on GTmetrix and Pingdom – you know what – that GeneratePress speed and performance always stay green with 98 – 99%! To be frank, I still couldn’t believe it. :O
Hands down. You’re impressive.
