If you join Twitter just follow me and say hi. I’m happy to help you with Twitter. If a writer follows me and says “hello I read your thing” (or words to that effect) I’ll pretty much always follow them back. Any sort of readerly, writerly, creative person is welcome so long as they’re reasonably funny or friendly. I draw the line at people who look like they were sent back from the future to kill me but that’s about it. Every writer should be on Twitter. As for Donald Trump? Yeah. Some people should not be allowed on Twitter. Some people shouldn’t even have access to a phone, never mind the nuclear codes.
