Copywriting is Interface Design  Every letter matters
Copywriting is interface design. Great interfaces are written.
If you think every pixel, every icon, every typeface matters,
then you also need to believe every letter matters. When you're
writing your interface, always put yourself in the shoes of the
person who's reading your interface. What do they need to know?
How can you explain it succinctly and clearly?  Do you label a
button Submit or Save or Update or New or Create? That's
copywriting. Do you write three sentences or five? Do you
explain with general examples or with details? Do you label
content New or Updated or Recently Updated or Modified? Is it
There are new messages: 5 or There are 5 new messages or is it 5
or five or messages or posts? All of this matters.  You need to
speak the same language as your audience too. Just because
you're writing a web app doesn't mean you can get away with
technical jargon. Think about your customers and think about
what those buttons and words mean to them.
