Aphantasia: How It Feels to Be Blind in Your Mind
I'm the author of this post, happy to answer any questions.<p>About me: I was formerly a director of product at FB and a founder of Firefox. My YC startup became FB's first acquisition. I'm focusing more on creative writing these days (wrote the Silicon Valley spec script and the Theranos parody that have come up on HN a few times.) Aphantasia was a pretty weird discovery for me given this new focus.
