People always point to email as a decentralized system that works. They forget that originally nearly everyone got email through their ISP, and now nearly everyone gets their email through their OS vendor (Google, Apple, or Microsoft), or for businesses one of the few commercial mass mail services like mailchimp that don’t get blocked by spam filters. Self-hosting email is likely to result in a major hassle with undelivered emails due to anti-spam measures these days.

Decently readable, though some of the letter forms you’ve chosen could be confused for others (‘a’ is quite similar to ‘o’, ‘f’ could be confused for ‘t’). When I’m lettering for engineering/math I use engineering gothic letterforms which avoid these ambiguities, among others (I vs l vs ι vs 1 vs 7, a vs α vs o vs ο, O vs 0, q vs g, k vs κ, v vs ν, u vs μ, B vs 8). When I’m handwriting I just write chickenscratch unreadable to anyone else including my future self after a year or so.
