Advice | Miss Manners: Journalist posts on social media about a typo at another outlet

Dear Miss Manners: I am a journalist. The other day, I noticed a typo in an online headline from another outlet, so I called around to see if I could notify them. I was unsuccessful. Eventually, I posted on social media that they should fix it. I only meant for the post to be up an hour or so, but I got busy and forgot to take it down.
