IMHO the word high is an useless way to describe your resolution.
We're scientists. We measure things. Things called numbers. So why
not use them?
The words high and low are about as useful in scientific literature
as large and small, many and few, old and new or the
ever-popular

I don't think the term high resolution has any real definition or
meaning anymore. If you're proud of the resolution, put the number in
the title of the paper and let the reader decide. At one time 2 A was
high resolution, but I wouldn't consider that high resolution today

Actually, if you want to feel really good, I learned (in the context of
optics) that you can resolve two points separated by a distance x with a
diffraction limit of x/0.7
Of course. However, C=0 bond is ~1.2A, and bonds made by those pesky
hydrogens are ~1A. And I would think (it is semantics again) that to
reach atomic resolution you have to resolve all atoms, otherwise
All atoms are equal, but some (non-hydrogens) are more equal than
others.

Sure, it has very little to do with original question about what
constitutes high resolution. And that term is quite relative. 1.8A
data is definitely of higher resolution than 2A, but is it high? (Not
to mention the issue of subjective choice of resolution cutoff). The
only way to define

A less radical view (pun intended) suggests two. ;)

I think this is coupled with the data completeness. Say you have a data
50.0-1.0A resolution, but the completeness in say 3.0-1.0A resolution
range is equal to 10%, and it is 100% complete in 50.0-3.0A.
