In Silicon Valley, it's all about keeping score. The question entrepreneurs are asking about Sarah Lacy's Web 2.0 book: Am I in it? And how many pages? Michael Wolff's chronicle of the first Web bubble, Burn Rate, had a clever conceit: The index was published online at burnrate.com, driving people online to see if they were included in the tell-all, and then to the bookstores to see what Wolff had to say about them. (Too clever by half: The website is now abandoned, and there's no trace of the online-only index.) Lacy's instant history of this frothy time, Once You're Lucky, Twice You're Good, could benefit from having its index published. The book is coming out a week from tomorrow, but it's already in the hands of most of the people she wrote about. Don't you think the likes of Kevin Rose, Max Levchin, and Mark Zuckerberg are counting the number of pages Lacy devoted to them? Soon you can, too. I'll be running all the pages from the index here over the next few days.
