A bit of background:
This question was locked to stop the cycle of close, reopen, close, reopen...
(The question is irrelevant. It's just an example)
But, apparently, you can still add answers to this question. I didn't even know that was possible. I thought the entire thread was locked down. I'm assuming a lot of people would make the same mistake.
Might I suggest that most people don't know what it means (or don't care) that a question has been locked. It could be confusing to users and potentially harmful to the question.
The solution would be to remove the general notice and just show a descriptive popup if someone tries to click the link of a "locked function." In this case, clicking on the
close link pops up:
A moderator has disabled closing for this question.
[click to dismiss]"
It avoids the confusion and avoids "branding" the question in a negative light (everything looks "normal" to most users).
'Just a random thought about usability and the user experience.
