Today is April Fools’ Day, which means the Internet will be filled with random pranks. Case in point: Twitter’s announcement of Twttr, a new level of service where consonants are free, but users will be charged $5 a month for the ability to use vowels. From the company’s blog:

Starting 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.
