- How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?
Why this question? I didn't see this kind of problem on Arduino SE or Stack Overflow. Any longer comments exchange is moved to chat.
- How would you handle a situation where another mod closed/deleted/etc. a question that you feel shouldn’t have been?
First I want to say it didn't happen here that I would feel a moderator shouldn't take some action except of declining my flag one or two times. I asked about it (on Meta) and I got an acceptable answer. If as a moderator I disagree (very strong) about an action of other moderator, I hope there is way to talk to other moderators and express the disagreement and hope for explanation, but I will not start an argumentation fight or revert the action myself.
- In your opinion, what do moderators do?
Moderator's mission is to guide the community. Users better accept instructions from a diamond moderator.
Moderators duty is to handle flags: flags on Questions, flags on comments, flags on Answers.
Moderators can close/open/delete Questions immediately if there is a good reason to do it. Moderators can migrate Questions to other SE sites and accept migrated Questions.
- A diamond will be attached to everything you say and have said in the past, including questions, answers and comments. Everything you will do will be seen under a different light. How do you feel about that?
I like it
- In what way do you feel that being a moderator will make you more effective as opposed to simply reaching 10k or 20k rep?
On Arduino SE all useful community moderation privileges are achieved at 4000 rep points. I reached that in September 2018. I use the with privileges available moderation tools.
As moderator I will take action instead of flagging.
If 3-vote closing stays, then there will be less work for moderators to maintain Questions, but some off-topic question would be better to close sooner than required count of votes is collected.
I would like to migrate more Arduino specific Questions from Stack Overflow and EE SE. Maybe as moderator here, I can do it more efficient.
