What if Mark Twain was on Twitter? I mean, technically he is, but Historical Tweets also gave a humorous answer to that question:

So true.
For those wondering, DeQuille is short for Dan DeQuille, the pen name of William Wright. Wright was also a writer who worked at the Virginia City Territorial Enterprise with Twain in the 1860s, and they were the paper’s star writing team. The two became great friends and maintained correspondance long after Twain left Nevada.
Still corresponding today I see, although in much shorter form.
The background image for Mark Twain’s Twitter seems to be of the W. M. Black steamboat, which paddled up and down the Missouri River for 37 years, until 1973.
What is most interesting about the tweet though, is that it comes from a quotation that is often misattributed to Twain:
“I have made this letter longer than usual, only because I have not had time to make it shorter.” This quote is by the 17th-century French philosopher and mathematician, Blaise Pascal (1623-62), written in a letter to a friend. The original French version was: “Je n’ai fait cette lettre – ci plus longue que parce que je n’ai pas eu le loisir de la faire plus courte” – TwainQuotes.com
But it sounds like something Twain would write, doesn’t it?
