The lost art of proof-reading

Does anyone in newspapers proof-read any more? Long gone are the days of copyholders and readers but there still needs to be time left for someone armed with a ruler and a pen, to go through the pages in detail and make the corrections. It would certainly have saved the Citizen & Times its recent embarrassment.   Anyway, here are two proof-reading videos. One is to make you smile, the other is a more serious guide to proofing marks. The latter will surely be redundant soon. If you are reading a proof why mark it up for someone else? Just do it yourself.
