Why is it that so many people leave answers in the "comments" section, as opposed to the "answer" section? (You may leave your answer in either section 😉)
Mi Yodeya has very strict quality standards. When I have an answer which is not of high-enough quality - for example, it lacks sources - I often post it as a comment. When I do post it as an answer, it gets downvoted quite quickly, or attacked. I wish the site was friendlier... But as it is, I rather post it as a comment then get negative feedback for posting it as an answer.
I leave comments that are undeveloped answers so others can build on them to make an answer if they want.
If I don't have an answer at all but have some information that can lead to an answer, I will often post it as a comment.
I will usually leave a comment when I have no formal source for it, as a proper answer needs a source.
Usually more of "I heard from my Rabbi" or "a Rabbi" which I guess is a source for me but not one suitable for Mi Yodeyah's answers. Of course, perhaps I should go to my Rabbi and ask him for the source that I am going to quote. But then maybe he heard it from his own Rebbe...
True Torah She'baal Peh still exists..
