Not that I use the local YP much, but it probably depends to a large degree on how often you need local services like plumbers etc. To be sure, even as a homeowner, you tend to compile your own rolodex (to use an anachronism) of local service companies to use but every now and then you need something different that may not be easy to find on the Web. (Web presence is still very [EDIT] hit or miss for a lot of local companies.)
