Greetings, As you all might know, the Haskell community has it's own informal magazine, The Monad.Reader (http://haskell.org/tmrwiki). I'm planning to write (with some support from the frequent users of #haskell @ irc.freenode.net) a series of articles for TMR, which describe some aspect of Haskell. Because of the informal (but serious and thorough) style of TMR, I'd like to do this using a top 10 list regarding some subject. Every article will list 10 of most famous, most frequently used or most usefull things regarding that subject. I'd like to ask for suggestions on each subject when I'm writing the article on this mailing list, because I don't know the Haskell world very well (I've only been working with it for a year know, in my spare time). This first mail is intented to ask for suggestions regarding future subjects for the articles. Suggestions are welcome by replying, or by adding them to the 'take 10 [1..]'-wiki at http://haskell.org/tmrwiki/TopTenHaskell . Also other suggestions or remarks are very welcome. I hope this series of articles can provide a source of information for both new and experienced users, because you there's always room to discover new aspects of your favourite language.
