A few months ago Rael Dornfest asked me if I would like to contribute to the second edition of the Google Hacks book he writes for O'reilly (he's actually in charge of the entire "hacks" series). More specifically, he wanted my input and knowledge as it pertained to Gmail, because there was going to be an entire chapter devoted to the webmail service in the new book.
After doing quite a bit of research I organized my ideas and findings and gave Rael everything I had come up with. A few days after I submitted my work, he asked if I would like to be the technical editor on the book. I of course jumped at the opportunity and really appreciated being asked to take on the task. I'll admit, it got a little hairy there for a while trying to juggle my commitment to the book with law school and interviewing and this site and... you get the idea. Notwithstanding the time crunch, I would do it all over again and am actually in the process of making that happen.
That said, go out and buy the book — I thought I knew a lot about Google, but after poring over this book from cover to cover I realized that I was quite ignorant (not anymore!). Word from the top is that it should be on shelves by the end of the year.
