Getting a high page rank is very dependent on who links into you and their page rank. The more pages of high value linking to you the higher your site will rank. Think of it as not what you know but who you know. The Yahoo! Directory is a site that is ranked about as high as one can get. So getting a listing in the Yahoo! directory can have very good benefits for your site in addition to the traffic they send you. However, the traffic they send you will probably not be significant. Back in the day, many people used the Yahoo! Directory as it was the home page of Yahoo!. Well those days are long gone and the Yahoo! Directory appears to be dying slow death. Currently Yahoo! charges $299 to get listed, which brings us back to the question, "Is it worth it?" The answer is Yes and No. We would advise no if you have a moderate budget of less than $3000 a year. 10% of your budget on Yahoo! is a waste in light of other strategies and pay-per-click opportunities. However we would advise Yes if your budget is higher, as it may make sense to get the listing and the associated rank value if it is a small part of your budget.
