These kinds of bare HTML pages are better than many sites, but a very welcome alternative is applying just a bit of CSS to keep the width of the content at a readable length, apply a bit of spacing to the text between lines so everything isn't bunched up, and a few minor touches like that to enhance readability and make the page look aesthetically nicer.

You can go really, really far with less than 100 lines of CSS essentially.

Yeah, but they'd be even better if they were more like:

I actually find this wide text hard to read.

I think they're great - they remind me of what the internet was like before the marketing departments showed up.

Love it. I find the harder the hardcore Unix(-like) or CS geekery is, the more likely you'll find pages still like this.
