The font doesn't seem that great to me. Not sure exactly why but while it's not quite difficult for me to read, it's not as easy as other common fonts.
I think that's kind of the whole point. It is introducing an ambience, it is deliberately made quirky and irregular like the handwriting of some. It is not a common font and that means our eyes are going to be slightly unused to reading it.
The font is fine, it's the line-height that is wrong: the text is a bit too squished
Oh I see what you mean
You are welcome to use vanilla frameworks for a generic looking site. This is clearly intended as a thematic look.
Yes, but it shouldn't be to the point that it gets in the way of the content. But I'm not a web designer and I'm not the intended audience. Still, I like to click through to interesting (to me) things and check them out. The typeface kept me from investigating as far as I normally might.
Why can't I use this one? I don't see anything mentioned about the font being required or even part of it.
