I like the idea of the pixel font, but find one that doesn't make the N look ugly. Silkscreen's usually a safe choice.<p>And I'd make the dev account more than 100 hits/day. I could easily go through that while actually coding, fixing bugs, repeat.<p>Since the use case is about quick, lightweight projects, I'd make creating an account optional until you need it. I'd want this to be as frictionless as possible, so that if I'm in the throes of coding and want the simplest possible key value store, I can just type in a URL like <a href="https://tinycache.io/api/myemail@address.com/CACHE_KEY" rel="nofollow">https://tinycache.io/api/myemail@address.com/CACHE_KEY</a> and know it'll work without having to break out of my editor.
