Add "Community and Help" section

• How do I find a library?
• How do I find a solution?
• How do I find the most idiomatic way to solve this problem in Haskell?
• There are numerous blogs with new ideas (Comonad Reader etc)
• There are many user groups in different languages in IRC, Gitter, Telegram, Facebook - you name it.
• StackOverflow has 3 useful sites for a Haskeller: StackOverflow, CodeReview and ComputerScience (and what is more important is that if you ask a harder question which only Edward Kmett or Don Stewart can answer they probably will there, up to the point of https://ro-che.info/ccc/2)

Yeah, I think this is a good idea. I think another useful thing would be some rough rules of thumb for evaluating library quality (i.e. number of downloads, documentation quality)

This section should probably also include Documentation (Haddock etc.), or do you think a separate section would be better?

I agree
