Your site should be usable without styles though, if only for SEO reasons. Think about how Googlebot reads your page - does it read the styles? Making your page work without styles is by no means 'useless'. Having said that, the Mosaic test probably isn't worthwhile as it's severely out of date when it comes to HTML; at least Lynx is actively maintained.
