Is there an easier way to interact with a migrated question where I
don't have an account?
It's only "migrated" on Skeptics, on Beer it's essentially just a question as if you'd originally asked it on Beer.
You're essentially asking "Can I use a site even though I have not registered", well "no" that's not how the sites work, and migration does not really change the reasons for needing to register.
I see no hardship in having an account even if only for this question. How do you decide when having an account on a site is viable to you? When you will ask 5 questions? 10? When you will ask and answer 10 questions? This makes no sense, you have a question on Beer which you wanted an answer to (albeit migrated from Skeptics), is this not enough to warrant an account?
If the single question (now) on Beer is not enough to warrant you opening an account on Beer, then your question here (MSE) is largely pointless, as either you don't care about your question on Beer, so forget it, or just open an account because it's important to you.
I feel that I should have some amount of control over my own question
when it's migrated
Well, it should not have been asked on the wrong site, to be fair, however in terms of your "control" you can:
- Ask to be disassociated with the question (on Beer), i.e. if you
would not have opened an account to ask on Beer
- Open an account on Beer site (simple and quick to do) and manage
your question with ease
- Leave it and forget it ever existed
I think this is a fair amount of "control", especially when considering site "scope" and "topic" is site specific and is pretty well documented (you did ask on the wrong site).
I also don't think there should be any change in the system to somehow accommodate users being able to interact with their question migrated to a site they do not have an account with.
There are reasons we need to register and migration doesn't change this - there is no way to use the stats and privileges (etc) on the site it was migrated from and use them on the site it was migrated to - they're two different sites and you need a separate account on them both.
