forum.cardano.org is a good place to raise questions related to pool operation or any technical question related to wallet usage, or anything.. also there is a official Telegram channel where you can ask anything.
My problem with Telegram is hard to find already answered questions.. And forum.cardano.org can not be moderated as good as stackExchange site in terms of editing questions/answers, flag something if duplicated or can be closed if not related...
So if there will be a cardano stackexchage site should members of the forum/telegram be redirected to here if there have specific questions?
Proposal: Cardano
