My blog is more minimal, and still viable. It's just a big page with 761 posts on it. It's 360 KB all in, and it's interactive in about 1 second.

No category pages, no individual pages. No search... well, CMD+F is your search engine, and it's blazingly fast.

That design actually works really well if all you care about is getting text content out there, and the idea of comments—let alone ads—isn't appealing to you.
