I took a look at the recently-created tags in the Moderator Tools (on SO) and clicked on one of them. When I then clicked
learn more... to see the tag wiki, it said:
Thanks for your edit!
This edit will be visible only to you until it is peer reviewed.
The strange thing is, I wasn't the one who proposed the edit, and the edit was not visible to me. I checked a couple other tags with pending edits, and it seems they all have the same strange behavior.
