What do Paul Graham and Jason Fried have in common?

Or at least: what do both of them consider of the utmost importance when hiring someone?

Good writing abilities.

Paul Graham writes:

I think it's far more important to write well than most people realize. Writing doesn't just communicate ideas; it generates them. If you're bad at writing and don't like to do it, you'll miss out on most of the ideas writing would have generated.

Whereas Jason Fried writes this:

If you are trying to decide between a few people to fill your position, always hire the better writer. I don’t care if that person is a designer, programmer, marketer, salesperson, whatever. Assuming your candidates are fairly equally skilled and qualified overall, always hire the better writer. This is especially true with designers since copywriting is interface design.

How come both of them value the writing abilies of the people so much?
