In the era of immediate hyper-personalization, you could.not.possibly write with the same fonts as everyone else. Really, now that a documentary has been made about Helvetica, what kind of indie cred can it have left? Luckily, you can design your own fonts, with new programs like those at FontForge, some of which are free. Not selfish enough for you? For $200 or less, you can have a professional at Chank Fonts, High-Logic or FontLab make your Twitter even more you-centric.
