Is Yahoo! still useful?

[CMUNSON]

     Yahoo! has been one of the premiere web directories for several years, 
     but I'm beginning to wonder if it's really up-to-date. Does anyone 
     know of any articles or studies on Yahoo! or its content? I've 
     submitted web sites half a dozen times to Yahoo! and they never got 
     added. One was work-related and I asked 4 times over 6 months. Given 
     the exponential increase in web content you'd think you'd see a 
     corresponding increase in the number of new sites added.
     
     I see little evidence of this at Yahoo!
     
     Any observations?
