About the usefulness of libraries: I just made some statistics
on imports in Haskell code; I have a lot of Haskell source code
on my disk (mostly downloaded).
In the following table, the number on the left indicates the
number of imports found for each library.
Top twenty of imports:
418 Data.List
417 System.IO
288 Data.Char
274 Control.Monad
157 Data.Maybe
150 Graphics.UI.WX
144 Control.Exception
118 Test.HUnit
105 System.Directory
103 Data.Word
101 Prelude
95 Text.ParserCombinators.Parsec
84 System.IO.Error
83 System.IO.Unsafe
80 System.Exit
79 Data.Array
76 Graphics.UI.WXCore
75 Data.Bits
73 System.Time
73 MissingH.Str
Total number of imports: 8691
Total number of files: 1918

Only a few of the standard libraries are useful unless you are doing
something specific. i.e. Data.Maybe is generally useful, but
Control.Monad.State is only useful if you are using a state monad.
If someone wrote a tour of Data.List/Data.Maybe as well as a few
common functions out of Control.Monad that would probably make a nice
companion to a tour of the prelude.
Thanks
