Typefaces aren't trendy/trending per se
.
I would disagree with this. Whilst it's true there are classic typefaces that are perpetually popular and heavily used, there are also swings towards use and disuse of certain typefaces/type styles at certain times.
Recently for example I have noticed an increase in use of classically proportioned geometric faces (mainly in advertising), as well as a new interest in humanist/calligraphic sanserifs for all purposes including text.
I wonder if Louise is still around and wants to continue the discussion, as I'm always ready to gossip about fonts, but I'd need to know what type of typeface she has in mind before recommending anything.
Berry -- what do you mean by 'designer' fonts?
