Yes, comments from Slashdot are used. They are short, terse quotes that provide in /no/ way indentification. That would cross privacy boundaries I'm not wiling to cross. We choose to use them to try and express to the rest of the world who will read this book the sort of things that happen to real people.

I tried to contact some of the commenters originally, but ran into dismal success. As well, many people were posting anonymously. Obviously, they were impossible to reach.

So - summary: Yes, comments were used. They were posted in a public forum, which means that anyone can quote from them - but we've removed any sort of identifying marks, to protect people. This was down to impress upon those reading the gravity of the situation.
