Helpful hint. It's hard to delete all your tweets if you have a lot, like I did, without a paid service.
So I downloaded an archive of my tweets.
Changed my user name, then deleted the account.
Immediately opened up a new account under this name, so no one could steal it.
This is me, the host of NPR's "Wait, Wait, Don't Tell Me." I now am over on Bluesky, @petersagal.bsky.social, and will only be posting there. Accept no substitutes. Or, you know, go outside.
