Why is the default font bold?

The default font (Bariol) used in the lessons in the web version of LingQ is bold. This is caused by the following CSS code:

.sentence-text.font-style-0 .sentence-item { font-weight: 700; }

The other two fonts are not bold (the CSS property disappears when you use them). Why is that? For Latin-alphabet texts, I guess the bold font is OK (although still a bit hard on the eyes), but Greek texts are way too bold. Wouldn’t it be better to make the default not bold?

Thanks for pointing that out. We will look into it, it has been reported to our developers on the day you created this thread.
