Love it, I hadn't seen it yet. I've been trying to handle links to tutorials, links I find while reading tutorials, resources that might be useful later when I'm already familiar with what I'm trying to learn, and it was clumsy. Tried Delicious, Kippt etc, but a focused service is much better—and more likely to have good links from other users.

Already found some interesting tutorials and posts while searching for something I intend to start learning this month. Thank you.

Addendum: a problem I've found while trying to find good learning material is that of the unknown unknowns (https://en.wikipedia.org/wiki/There_are_known_knowns): when you're starting out, you don't know what you have to learn yet. Maybe guides that tell you what you have to learn, in what order... A way of letting the user organize tutorials that lets the user "patch" holes in their knowledge by adding other tutorials, or revisiting some tutorials... Well, this is beyond the scope of Pineapple, but it's an interesting problem to think about.
