1. This reminds me that there used to be quite a few pages indexed by Google that were just *.txt. Remember Brett's "blog" on WmW that was .txt?
2. Old HTML 3.* (pre CSS) web pages are almost bulletproof. Generally the image files get lost but all the text is still there. I see some of these sites, many rescued from Geocities, that are still ugly but viable and I laugh a lot less at MS Frontpage 95/98.
3. CSS should have been more of a plain markup language, if that is possible. CSS became another hurdle and barrier to the personal webpage and encouraged the adoption of blog platforms.
4. Feh, on CSS.
