512kb is huge :-) Still, made me look at my home page again. About 77kb, of which 51kb is fonts. I think you can go down a rabbit hole with this when the basics are already there, but system fonts, webp images etc. etc.
The 512KB Club is an exclusive list of web pages weighing less than 512 kilobytes.
I should add my blog to the 512k club. Confirming I'd quality and noticed I'm loading a gravatar image (likely in my h-card) in 2 different places but not displaying them – I wonder if I can modify that somehow to provide the url but not load a hidden image....
