I joined Twitter in 2009 in the futile hope that it would lead me to a Korean Taco truck on my first ever visit to LA. It didn't occur to me to tweet until 2021 when I decided that it was time to launch a quixotic attempt to get Bialetti to revive their legendary pasta machine. This failed miserably too, although the Guardian food columnist Racheal Roddy was very nice about it.
Since then I've tweeted a few times always in response to something someone else had written. This led me to wonder why I couldn't bring myself to originate a tweet. The answer to this query appeared to me yesterday in the form of a talk delivered by Frank Ramsey in 1925 that appears as the Epilogue in the collection of Ramsey's papers edited by R.B. Braithwaite titled: "The Foundations of Mathematics"
