Yesterday I changed my Twitter handle, today I want to test, what happens if I do not update the change on WordPress and publish a blog post.

I expect to happen one of these:

1. cannot publish blog post
2. cannot publish blog post, error message that there is no such handle
3. can publish blog post, but no tweet on Twitter
4. can publish blog post, there is tweet on Twitter for ghost account with old handle
5. can publish blog post, tweet on Twitter with new handle
6. something else

UPDATE after the test

Test was successful. Blog was published with right Twitter handle.

What I like a lot, that WP updated automatically to the new handle. If I choose to write another blog post than it is already filled with the new handle. No human interaction necessary! 

Update: I found one thing that broke – Twitter widget in the sidebar.
