Here's my new hobby which you #TwitterMigration folks might also want to try.
Watch your Local timeline for people just arriving or making their first post. (It's not stalking. Really.)
And then reply with something like, "Hello and welcome! 👋"
Sometimes that starts a conversation. Sometimes you wind up following each other.
Why do that? Maybe to be as kind as all the wonderful folks who welcomed us here?
So, go ahead. Pay it forward. Make a new friend. It's fun. And, you know, social.
