I read carefully; I find the Author's Alteration pages to be harder, though. Most other page proofs I've proofread are essentially what the printed page will look like. The AAs, as they are affectionately called, are double spaced Courier, in 12pt, with line numbers down the left side.
I work in Courier, and so this looks like manuscript to me, and it's much harder for me to see the things I actually typed (as opposed to the ones I thought I did) in this format. I would almost pay money to see the actual page proof pages because I think I would catch a lot more than I obviously did.
On the other hand, I'm almost resigned to missing things. Because, of course, while rereading parts of Secret for background for a section of Chaos, the first thing I noticed in the published book was... a typo. V.V.
I also have GST return forms, but I have to get the AAs back as soon as possible (and honestly, I would rather read these than do the taxes).
So... I am sitting in front of my computer, making a post instead of continuing to work on them. This, sadly, is the fine art of procrastination. I also created a Twitter account. Because, yes, procrastinating. I updated my very under-updated web page. Someone elsewhere used the word "multi-crastination", and I find myself living up to it...
