Huge typography is obnoxious, from marketing philosophy standpoint - it screams insecurity. From a technical standpoint, it is inappropriate for the screen size. Yet designers today love choosing HUGE typography to be bold and daring. From Dropbox to IBM, from GS to Apple - this whole trendy huge font thing bothers me.
I understand that they're using huge font sizes to show off to the world their new typeface. Make no mistake, it will be used in huge sizes as it is the current trend - a cool thing to do as a designer is to employ massive bold typography today.
