I'm not a good creator so probably I can't give best advice here. Introduction is for the first appearance so a good starter for series about yourself.
That tag is good for personal story, I'm not sure if it's good for FAQ (might be too long, too boring)
For example I don't care about LGBT topics at all, I'm looking for a good content, such as interesting story. Yours sounds promising. Then I guess I will have questions that I'd like to find answers for, some of them for sure are from "Frequently Asked" cathegory.
Where to put that?
I don't know.
Current UIs doesn't really have anything but simple user profiles.
Separate post that you could reference to later on?

I kinda messed up here by posting in #introduceyourself by mistake, is it worth reposting in the correct category you think?
Anyway, there it is - i'll probably leave it to be honest, i'll start writing up my story post too.
It's ok. Having #introduceyourself as one of the tags is enough.
