Yesterday, I got an odd message from LinkedIn, congratulating me on my recent job change. 'Cept, of course, I didn't recently change jobs. Random/whatever. Today, I got this:

Hi Michael,
Whoops – we made a mistake.
Yesterday, you may have received an email regarding a recent job change. We apologize, as we did not mean to send you this message.
We hope that we can continue to support you in your professional endeavors and look forward to celebrating your success.
Best,
The LinkedIn Team

Maybe it went systemwide, which would be one prolific screw-up, and maybe all the LinkedIn-ers got the same message. It's not even a deal, never mind a big deal. But weird, right?
