A monoid is a pipeline of functions. e.g. cat x | sort | uniq ; or F(G(H(x))). A monad is a monoid with smart pipes.

I have no idea either so I thought I'd Google monoid http://mathworld.wolfram.com/Monoid.html I kind of understand that but that's scratching the surface. Can you recommend a good book or article that covers the basics of FP (one written by a subject matter expert)? That would be much more useful
I recommend using IRC to go through the subject with examples. http://qfpl.io/contact There are two questions: 1. what does it mean? (easy) 2. why do you care? what is the practical purpose? (takes some socratic discourse) I am at lambdaconf (Boulder) in June if that helps.

The why is easy. We're heavily invested in event sourced CQRS. State is restored by replaying events (left fold?). I want to learn more. Without joining a club.

I do not believe the second question is easy, if you are to gain a deep understanding of the answer. I cannot do tutorials on twitter.
