Who or whom in this sentence?

Wait and see who it appeals to?
Wait and see whom it appeals to?

It's not a very formal text.

Yes I realise that it would be correct to say "Wait and see to whom it appeals", but as I say it's not a very formal text. So we're not doing that.

If it's not a formal text, and you don't want to get it 100% correct, why do you need it to be 50% correct?

"To whom it appeals" is correct. Anything else is wrong, so it doesn't matter which you use.

If you don't want to say 'wait and see to whom it appeals' then use the first example, with who.

'Wait and see whom it appeals to' is wrong, and it sounds wrong, whereas 'wait and see who it appeals to' is, admittedly, technically wrong but common usage makes it sound right to most people's ears.

Whom.

A quick tip I learned was that if the answer was "me" or "him" or "her", in this case "It appeals to me/him/her", then you use "whom".

"Wait and see who finds it appealing"?

Whom. It would be grammatically correct then, but clunky and inelegant, as well as offending people who think (erroneously) that you can't end an English sentence with a preposition. I'd go with prism's suggestion.

Or wait a few years. The who/whom distinction will be gone the way of thee and thou.
