Some time ago I discovered the 512KB club. It collects performance-focused websites from across the Internet.
Qualifying sites must fullfil two requirements to participate.
The site must provide a reasonable amount of content.
And the total uncompressed web resources must not exceed 512KB.

512KB Club is a nice resource to discover more niche sites on the Internet.
Often these are handcrafted personal sites and blogs with unique content.
They remind me of all the unique personal sites and blogs from before the web2.0/social-media/walled-garden time.

My blog is also very lightweight (currently clocking 39.48kB on the Cloudflare URL Scanner), thus I submitted it for inclusion in the list.
It was accepted recently and is now listed as part of the Green Team (sites smaller than 100KB).
