Yesterday, the page indicated there were three comments. I typed a fairly long one, clicked the button, and the page replotted. Still said there were three comments. There is no mention on the page that comments are moderated. There was no "success" message telling me that my comment had been submitted.
After a couple of hours I checked back, and still saw that there were three comments. Thinking that I might have done something wrong, I recreated my comment (should have kept a copy in a document, but I forgot) and posted again. Same result.
As one who used to design user interfaces, I find this unacceptable on the part of Yahoo. If comments are no longer being accepted, there should be a message to that effect and it shouldn't be possible to attempt to submit a comment (No comment input field.)
If comments are being moderated, there should be a permanent message displayed to that effect. After clicking the button to submit, a feedback message should be displayed, verifying that the comment has been received and telling the user that it will be posted later if it is approved.
If comments are not being moderated, the comment should appear immediately after submission.
For all I know, my comments fell into the bit bucket next to the server.
