"In" doesn't necessarily lend itself to snappy English phrases like "to" does. It might also be confused with the gerund, especially when spoken - do I go to meet.in or meet.ing? And what's your company/product called?

And are there additional restrictions on Indian domains? Not sure. For example, last time I checked, only Americans could register .us domains.

it is a great tld (I have one and a whole project that could be formed around it, just dont have the time to get it done. I need a Zed Shaw crash course on getting shit done).
