Yes.
Thanks for this analogy. Made me chuckle.

The last thing you want is your emails going to a wrong tld:
me@example.im
going to
me@example.in
is very likely in your scenario for less tech-savvy contacts IMO.
I think I will keep first-name .in and .net and let the nick-name.im expire after a year or two and share .net email to my contacts.
