I thought the fact that the grandparent was posted 20 times within 5 seconds made the meaning rather obvious.

It. Is. Too. Easy. To. Double. Post. Comments.

Many people do so accidentally and in fact it is the case that yesterday there was a list of about 50 most recent comments that were all multiply posted. This is a bad thing. I cannot make this any more clear and would not take further incomprehension of evidence that my meaning is not clear.

I note in myself a tendency to see some things I don't understand as "extremely bad", stupid, frustrating or etc., especially things that have changed recently from what I am used to.

Allow me to revise this. I can, in fact, supply instructions on how people are most likely to double post comments.

  • View any original post.
  • Find the comment box immediately below the post.
  • Write text.
  • Click "Comment"
  • Experience lag (like the entire site was experiencing immediately after the upgrade) or even just experience the slightly different commenting experience when commenting on posts vs commenting on other comments.
  • Click "Comment" again.
  • ???
  • Fail to profit.

That helped: we should disable the Comment button when you click it. Thanks for the bug report.

Please don't do this. In the event of a network failure, this can leave one unable to retry submitting a comment; I have actually experienced this on sites other than LW.

Instead, assign a unique identifier to each created comment form, and if the server receives two submissions with the same identifier, consider the second one an edit to the first comment. (Even client-side pseudorandom identifiers would be good enough for these purposes.)

Exactly!

(I thought that this was how LW already worked. My impression was that the code for replying to comments still has such a system and it is just the replying to the original post that is broken.)
