While the addresses are definitely too long to be fun to type, there are
still use cases where the addresses will be typed. So I think we should
consider everything which would make them easier to type and compare. 
Like others stated, base58 will not make the addresses easier to type, 
because they would be case sensitive.

But maybe it would help to separate them into groups of 4 characters,
separated maybe by a dash, which would make them look like this:
