Os dejo con ésta de Twitter, que me ha parecido bastante divertida:
Sunday, March 31, 2013Starting today, we are shifting to a two-tiered service: Everyone can use our basic service, Twttr, but you only get consonants. For five dollars a month, you can use our premium “Twitter” service which also includes vowels.
We’re doing this because we believe that by eliminating vowels, we’ll encourage a more efficient and “dense” form of communication. We also see an opportunity to diversify our revenue stream.
