mmegaera | another website thought

Should I really be that worried about how classy my website looks? Am I overthinking this in thinking that I need to find someone else to build my website or would using the templates my ISP provides for website-building be adequate for my first hopefully professional writerly website?

Doesn't the content matter more than the style, as long as the style is readable and reasonably nice-looking?

Or is that naïve of me?
