The Google Fonts service has been immensely popular with web designers ever since it first launched in May of 2010. And for good reason. There are no accounts to sign up for and no monthly fees like there are with other web font services. Just add a single line of code to your website and you have at your disposal a huge selection of free fonts that display beautifully on screen.

But all of this begs the question: why is Google in the fonts game? What do they have to gain by hosting fonts for millions of websites for free? Is Google in this for the long haul or will Google Fonts eventually end up in the dreaded Google Graveyard?
