I can remember when finding a typo in a published book was rare. I wish they were still rare. These days I usually find at least one in each book I read. Often they are obvious typos not just something spell check software could catch but something a human proofreader would have (or should have) noticed and fixed.
On the web there have always been typos, outright spelling and grammar mistakes. On the web we are writers without editors, proofreaders or back up staff. Most of us still write our own sites. We publish, maintain and do our own public relations and marketing too. We are our own tech support and once we leave the keyboard the whole operation leaves with us. So, there are uncaught typos, at the very least.
But the standards overall are slipping. Ignorance is part of it. You don’t need to be hired or pass a test to start publishing on the web. I think this has begun to infect the print publishers too. Why be so careful, so particular if you can get away with a casual typo or a relaxed style of punctuation, spelling and grammar? Why spend all that money hiring proofreaders to maintain a standard which seems to be disappearing?
I don’t like settling for less.
As a reader of print books the errors in print have begun to make me feel cheated. Once I felt I could rely on print publications to learn correct forms of writing. Now, I feel annoyed to pay full price for a book when publishers seem to have abandoned that diligence.
