Introducing T: A command-line power tool for Twitter 14 years ago
The thing that struck me is that there are no one letter commands in UNIX (that I can remember off the top of my head). Not sure if there's any reason for this besides namespace scarcity -- only 26 one-letter commands you can have!
It feels pretty arbitrary, I guess, to decide that Twitter is special enough that it gets to be one of the 26.
