Designer Viljami Salminen:
As I earlier in that article wrote, typography for the Web is really hard to design anywhere else than inside the browser. This is today even more true than it was a year ago. Typography prototype tries to solve this by doing the hard choices before jumping to other design tools like Photoshop.
Viljami really has a great point here. I’ve seen way too many projects backpedal when a font was decided on that looks awesome in Photoshop, only to fall apart in actual browser usage in the middle of a development cycle. But it’s more than face selection, it’s also issues of size and scale, also briefly touched on in this post.
