This question already has an answer here:

I didn't do anything abnormal here, except comment twice too quickly.

Chrome. OS X.

At first I thought it was a nerdy joke. But I guess it was a bug.

Confirming. Just tried it here and the bug appears as described. It seems to be overwriting the entire div containing the comment thread with some JSON, I assume returned from the AJAX query.



There seem to be some other UI bugs, presumably with the same root cause (tested in the Meta sandbox):

  • When upvoting 2 comments in rapid succession, previously a message saying to wait 5 seconds would pop up. Now no message appears (nothing at all seems to happen when clicking on the 2nd comment arrow).
  • Delete button does nothing (with no message) when deleting your comment immediately after upvoting another comment. (Probably the same as previous, since self-deletions are considered comment votes?)


This had the same cause as When trying to edit comments quick, error message pops up wrong, which is now fixed.
