Yes, this is correct about the SMS. Its also a love it/hate it element, but at the end of the day that's what makes it. Its the unique rule, the constraint, the sine-qua-non that defines what it is. Like haiku: without rules, a non-idea.

At functional level, forcing people to "think small, think short" actually works. Where people have short attention spans. As a mode for a 21st century communication.

Over time, people adapt and "think" thoughts in the language that they express. Be it poetry, or visually, etc. Or, if you speak a second language, you learn to think in the constraints of what works to communicate.
