I don't even disagree, but even people who couldn't get "What if I need to update the header on every single page" out of their heads just embraced framesets and "server-side includes aka shtml" (and the early highly-limited css) and called it a day. Without CMS etc
Yeah, I am not condoning writing HTML for most things, but for a personal blog where creativity is probably the top thing that matters, it's funny how tightly bound our thinking gets. Sometimes, I just sit back, step out and completely dismantle the status quo.
