If you clicked on this thread looking for real information, I'd highly recommend reading some of Aaron Wall's work on SEOBook.com. He just wrote an article titled What is a #1 Google Ranking Worth?. If you aren't subscribed to his feed, you need to do it right now. If you're looking for information on SEO, he's probably the most well-researched SEO that I've come across. He doesn't get into hype or buzzwords, he actually does testing and number crunching. I'm fairly confident that I wouldn't be the only one on this board to recommend his work, either.
