Binary takes up way more space when written out. Because binary translates to numbers, and those numbers will need to be translated into characters, the two people would need to settle on a common character set to ensure that messages can be properly decoded and not end up with the black diamond question mark symbol. Personally, I like UTF-8, but it might not be the best choice because some characters may take up much more space than others, resulting in a potential buffer overflow.
I remember I was still young enough when Myspace came out, being in someone's top 8 or whatever was a big deal... having your skin graft removed from someone's arm would have been devastating.
After touching two needles against a "special species of lodestone," they would become "sympathetic" to each other, and from then on always point in the same direction regardless of distance
