And about the "at least me" argument... I'm all for personal inspiration and taste in personal projects, and applaud you for following what you like. But you're trying to provide distraction-free writing for others, so you have to consider their characteristics, you have to consider what science knows about attention, reading and typing - not your taste.
I've noticed that you replied elsewhere that your typographic choice was also motivated by personal taste. Both noisy backgrounds and typography will deeply impact how your product performs in providing distraction-free writing. I think you can balance your personal touch with improvements in the fundamental dimensions of your product.
I'm sorry for the criticism, and I do support the initiative, but please try to align your product with your conceptual premises. Validate it, empirically. You claim it to be distraction-free? Try to get some metrics and subjective reviews, test with users. Also, you can stand on the shoulder of giants. There's literature about attention, even about typing.
