Considering the job you have has a massive impact on your personal happiness it makes a lot of sense to improve your odds of finding the right company to work for. The cost of careers.stackoverflow is nothing compared to the cost of actually taking an interview (easily 8+ hours). If because of stackoverflow you can get by with one interview less it's easily worth it.

Besides, if you have 3 great offers on the table I'm sure you'll be able able to negotiate a $100/year raise to recoup the careers.stackoverflow investment.
