Hi Thomas,
I agree with your general comments about the use of salutations and qualifiers.
I have commented on this before, but I have noted on the various PuristS channels, as well as other internet sites, that the use of qualifiers such as IMVHO, YMMV, IME, AFAIAA, AFAIK, etc., are used less frequently than they used to be. Even I use them less than I used to, but they certainly have their place.
They are particularly important in such a diverse group as ours. We come with different backgrounds and experiences, we speak different languages, we have varied cultural backgrounds and knowledge and I think these little niceties can smooth many unintended faux pas.
