Should I use acronyms?
by John Chapman
Some acronyms seem to be accepted - almost everyone would use '5,000 tons of TNT' rather than '5,000 tons of trinitrotoluene'. How about others though? How common must an acronym be before we use it in a book? For example should I write 'She checked her IM to see if he was online.' or write 'She checked her instant messaging program to see if he was online.'
