Yeah, I've read the entire website, but I still don't understand how a font for programming can be worth that much.
It's something you'll be looking at for perhaps 8 hours a day for years. If you actually use it, a font is easily worth that much, even disregarding its potential use in a commercial product. Of course, like open source software, free fonts do their best to undercut the market for individual professionals to make a living, but creating fonts isn't free.
I mean, what are you comparing against? Rendering text in the null font? Sure, if that's really all you have then I guess spend $250 on an actual font, but even VGA is perfectly serviceable for a lot of tasks, and I'm not sure this font is $250 better than VGA, let alone something like DejaVu or what have you.
>creating fonts isn't free
At this point we should ask if it was necessary to create another font in the first place.
