Ok, the guess collection for my book giveaway is closed! 180 people took a guess, and the number of times I used the word "Ethernet" in the book is 264.
Jesse Barnes of Brooklyn (coincidentally, one of my students) guessed 263, and Nic VanHouten of California guessed 265. Mr. VanHouten was actually first to guess, so I could have just given it to him, but since they are both the same amount off the mark I'm going to give it to both of them!
Here's the guess distribution:
Thanks to everyone who guessed! I will send out the $5 off discounts to everyone who entered shortly...
The emails went out at 5:34pm NYC time--check your spam folder if you haven't received it. I've also had a few bounces that I will follow up tomorrow.
