Okay interesting. Did you get stats on how diverse the majority of users' language is? I think there's also a second aspect. If I understand correctly, you're referring to the homogenisation of a single user's language (where 'Hope to hear from you soon' loses variation). I think the second aspect is homogenisation of language across many people. Did you look at tailoring the suggestions? In England there must be 30 ways to say goodbye, and this slang arguably is part of regional identity (although I don't know how much made it across to email).
