I have an auto substitution set up in iOS to automatically replace ?! with ‽ (Same for ellipsis, ... to …)

I'm not really frustrated, but it is annoying that I had to migrate accounts and stuff, but whatever.

And yes, I love the interrobang! Ever since I mapped scroll lock to "compose" on my keyboard, I've had fun typing all sorts of characters :)

It's a neat little mark but I don't think it has much of a chance being widespread because I think ?! has already won in real usage and doesn't have the fine detail problem. I think it has a better chance of becoming an official grammatical digraph than the merged mark.
