More fun facts:
Omitting those characters makes it good for generating passwords if they need to be typed in by hand.
Double-clicking a base58 string always selects the whole string and it doesn't wrap accidentally, thanks to missing / and +, so it's also convenient to copy and paste.
Unfortunately, no special characters means that a base58 string will often be rejected as a secure enough password.
