I'm still having trouble understanding when the "Not an Answer" flag should be used.
I recently flagged a couple of answers to Is there a short Daf Yomi shiur online in English? as not being an answer, where the question asked was (emphasis mine):
There is a short, 10-minute daf yomi shiur in Hebrew here : and I was wondering if there is anything comparable in English. I'm looking for a Daf Yomi shiur online that is significantly shorter than the normal 45-60 minutes.
The answers that I flagged (and downvoted) were all regular, ~45 minute Daf Yomi shiurim, which the OP expressly wasn't looking for, and don't answer the question at all, sometimes even acknowledged by the answerers themselves! One answer read (emphasis mine)
...He is amazing, one of my favorite teachers. However, it is not necessarily so short, since he likes to bring the opinions of many different Rishonim.
Another answer:
He is extremely interesting and covers the daf with rishonim in about 45 minutes.
I commented on some of these (but not all of them) on the spot, yet my flags were still declined.
Why is it that these are considered answers to the question, if they don't (attempt) to answer it?
