You – like this post author – are “…almost incapable of reading anything that [you’ve] written before. It’s just too boring when you already know what the next sentence is going to say; at best [you] can skim. So it’s very hard for [YOU] to catch mistakes…” WHERE – whoops, there goes a typo – where I substituted the second person in brackets for the author’s first person prose. USE THE COMMCENTER and trade papers with friends. It helps if you incentivize them. How about 25¢ for each typo? – you can probably come up with a feasible mechanism that won’t necessarily involve money. One might be “if you only find 3 typos in my paper, I’ll stop after I find the 3rd typo in your paper.” Or another might be “whoever finds the most typos…” or “can justifiably red-line the most prose” gets XXX.
