Often I start typing a question on SO and then figure out the answer halfway through. I used to just click discard, but lately it seems to have vanished. Where did it go?
The discard link only appears after a draft has been saved.
If a draft hasn't yet been saved, there's nothing to discard so no need for it. Just type in some text in an answer box and wait for a minute (45 seconds in fact), you'll see the link appear.
You need to have a few letters (even one letter as Mat explained) in the answer too alongwith some time for waiting.
A single line paragraph, such as my first paragraph won't make the answer to be (draft word appeared at this stage) saved as a draft.
But since this line, it appears! Saving the answer so that in case of any error your answer stays here safe. Which is a helpfull element for this website too! But, wait for it.
Try looking at the network tab to check all the network requests. And note the link that's known as
answer. That is the link which ensures that the answer was sent. It is located at
It generally takes 45 seconds for this request. So you need to wait atleast 45 seconds and check what happens. Discard will appear after the response from this link. Which is a result of whether you were writing an answer or not.
