I like Learn You a Haskell as a reference and cheat-sheet but I found it a little slow for learning Haskell.

Here's my recommended order for just learning Haskell:

http://yannesposito.com/Scratch/en/blog/Haskell-the-Hard-Way/ 80% completion here is fine if you feel your attention waning, the next thing will address hammering in things like functors and monads via typeclasses.

https://github.com/NICTA/course/ this will hammer in the lessons in a very direct form by forcing you to confront the challenges and lessons learned by the creators and community of Haskell itself. Doing the exercises here is critical for being fluent.

Real World Haskell is available online. (Thanks bos!)

Thoughts on http://words.steveklabnik.com/a-new-introduction-to-rust

1. Better than previous readings (though those were good too! Maybe just too quick?)
2. For visual learners, picturing/seeing chunk of lines is very useful.
2a. This becomes less clear across function calls. Any help in those cases? Similarly, investigation of hard to follow ownership examples will likely be valuable. 
3. A 3-4 point quick summary to figure out ownership in any context would be helpful. Not sure how possible this is, but if the essentials can be boiled down to something easily remembered and applied, the overall understanding can grow from repeated application of the correct rules.
4. Know of any editor support for showing ownership? At least in very simple cases it seems straightforward.
5. lifetime, ownership, borrow, etc. They seem to be good choices, but generic enough that they don't help until you already understand things. It might be easier to really nail home the concept and then finally say "and that? That's borro
