Tom LaGatta's talk on category theory at a 2014 LispNYC meetup, covering objects, morphisms and the basic ideas in an informal, conversational style. It runs about 97 minutes.

Why Hacker News points people here: Recommended as a more approachable introduction to category theory than the more formal lecture series people often start with.

Accessible talk introducing category theory.

I couldn't really tell you anything about category theory. But I am beginning to grasp monads. (At least in the context of Haskell programs.) I think the important thing is to see how they work, see what they do. btw, you might try this video: this video

“is also a nice introduction”

Nice introduction to category theory, pointing to nLab.

Category theory by Tom LaGatta[1] is also a nice introduction. He suggests taking a look at the nLab website[2], a wiki of Maths and Physics from the categorical point of view. [1] this video [2] link

Informal, conversational category theory presentation that is easier to follow.

nLab has been one of the best sources I've come across. My aim is to express and work with philosophical logic in a more formal way, and nLab is a great source for that as well. Milewski's YouTube lectures gets mentioned a lot, but I couldn't make much sense of them before watching Tom LaGatta's more informal and conversational presentation this video Good luck and keep at it.

Tom LaGatta in this video on Category Theory listed this website as number one resource on category theory. this video There he also lists some books on category theory. I am putting a direct link when he mentions the references.
