In case you missed it, Meta Stack Overflow spun off Meta Stack Exchange

Why is this a big deal? One of the changes is that your reputation on Meta Stack Overflow is now based off your reputation on Stack Overflow, instead of being independent[1]. So now you no longer gain or lose reputation on Meta Stack Overflow for questions and answers you post there, though people can still upvote and downvote your posts.

However, the new Meta Stack Exchange maintains its own reputation system, so reputation there still works the same way it did on the old Meta Stack Overflow.
