Clever is less than or equal to 140.

I'm reading The Evolution of Logic, by W.D. Hart. The book covers the last two centuries of philosophical and mathematical developments that enabled creation of the modern computer science, including principles built into software and hardware.
Out of curiosity, I decided to twit few quotes from the book. Here's what I got:

Since the sentence ( a quote from Burge describing Descartes understanding of self-evident truths) turned out to be longer than 140 characters, Twitter told me to be more clever.

It's self-evident that to justify an arbitrary limitation, Twitter has to associate this stupid limitation with a psychologically positive attribute "clever."
