serias -> series

[ceedubs]

Sorry, 2 kind of nitpicky questions/comments.

What exactly do you mean by "wonder series"? Did you mean "wonderful series"? If so, "wonderful" is probably fine, but it might be better to use a more objective description.

I'm a bit hesitant to say "should be easy for non-Haskell programmers to follow". Even introductory category theory and haskell can be a big paradigm shift for people, and I don't want to discourage people or have them feel bad about themselves if they don't easily follow it.

[kailuowang]

Those are really good points. Thanks @ceedubs!

[ceedubs]

Thanks for making the changes @kailuowang. This looks great to me.
