Evan Schaeffer offers cash bounties to readers who spot errors in his blog, Notes from the (Legal) Underground
What will you earn? $20 for each typographical error, $10 for each grammatical error, and $5 for each clever demonstration of how I can omit needless words.
Who is eligible? All readers. While before, I welcomed your e-mails and comments informing me of my stupid mistakes, now I'm going to pay you too.
Why am I doing this? Number one, I hate errors. Number two, I love the way good copy editors can make writing sharper and more focused. Number three, by giving myself a financial motive to improve my own editing skills, I hope I'll accomplish these goals myself, without having to pay you very much.
There are a number of conditions and exceptions, so read the rules before you play.
I would no doubt be broke if I tried this, just on the typos alone. But Mr. Shaeffer blogs less frequently, plus he is a practicing lawyer, so he can probably afford it. Plus, looks to me like he's actually quite careful—and even he's out of pocket $195 since starting this open-source proofreading thing about three weeks ago.
