Directories can work eg: Sportsbase and Brownbook both got investment, and TrustedPlaces sold for 2 million to Yell.com - BUT, these are exceptional ones, so dont think that just anyone can do this.
It will only work if you can get one out to the masses, but I dont think the all-purpose dirs have the unique selling point anymore to:
A) attract advertisers/give ROI
B) build the following/users/searchers needed to inject huge value.
