Welcome to issue 300 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers
from July 13 to 26, 2014
Looks like we are chuck-full of goodies this time around! Enjoy!

* glguy: There's no achievement for using all the operators
* benmachine: adoption by lots of people may stunt progress of
haskell, but it will probably help the progress of people
