My Dr of psychology wife, CELTA holder from her youth and officially tested genius, has a coffee mug some of her students gave her which reads "I am silently correcting your grammar
" ... which is so true.
Now myself I am not entering the deeply erudite argument laid here before me, however it does strike me that rather than the extraneous use of semicolons to the point of littering, that it may instead be useful if the majority could get their, they're and there correct. Further, for them to understand what a constitutes a sentence and paragraph, whilst throwing in any punctuation they can remember from their 3 weeks in education .... let alone semicolons.
Obviously I am a person who remembers life pre-internet. It was always my opinion that a great deal of the general population world wide were not overly bright. Yet the sheer amount who like to promote their ignorance and functional illiteracy by posting ignorant thoughts in barely readable drivel, is nothing short of astounding.
