Twenty-nine questions over twenty days might indicate scant interest in this little puzzler - even my curiousity meter is twitching around 'indifferent'.
So it's not connected to love, marriage, birth, death, academia, job development, sport or the performing arts - is not a well-known phrase or saying or an an 'award', per se?

[Chalky] Particular geographical location? NO, it happens in many locations.
[Chalky 2] Involves voting? YES, often.
[Chalky 3] Medical connection? YES and NO. It is not a critical connection but some of the most famous examples include a medical connection.
[Chalky 4] Possible 30 years ago? YES. And also 300 years ago.
*vigorous applause for the somewhat indifferent player*

I've given up.

I apologize. I guess I am really bad at this game. Next time i get the baton, I will just pass it on.
The AOTC is "verdict" -- in the legal sense, the finale of a trial, which involves some degree of performance on the part of both attorneys and witnesses...and which also involves voting, at least in my experience as a juror.

[cfm] Sorry you feel the need to apologise - there was nothing wrong with your choice really.
Something I've said before on more than one occasion ... I think it helps to reply to a question without changing the questioner's original wordage. Spinning a question forces a 'double read' which can get tiresome. It can also mislead, eg. your reply to CdM's key question regarding a specific profession didn't inspire a rigorous follow-up and perhaps should have?

[cfm] I've only been in the chair once. It can be quite difficult to respond to questions in a manner relative. Some people are quite adept at it. I wasn't. Don't dwell on it, regardless of the somewhat snide comments you might receive.

[cfm] Don't worry about it. I've made the same mistakes before, we all have.

To hurry things along I will pick up this discarded baton and offer an ABSTRACT with MINERAL & ANIMAL connections.

[cfm] Work of art? I would say Yes, but not everyone would agree.

[cfm] A thing, not a type of thing? Yes.
[Software] After 1900? Yes.

[cfm] Visual Art? I said before, not everyone would agree it was even art. That said, if it is art, it probably qualifies as visual art. (I am guided solely by Wikipedia in this matter, however).

[Rosie] A style? No.
[Dujon] Monumental? No. *Audience Mirth*
[cfm] Metalic? No.

[cfm] Intended as art? No, at least I doubt its creator(s) would have used that word at the time.

[cfm] Metallic association? No.

[Phil] man-made? Yes.
[Chalky] name of a place? *Audience Applaudes* Part of the AOTC is the name of a place.

[Chalky] Wet Stuff? No.
[Phil] Can you see it in a specific place? Yes, I have seen it in several specific places.
