This week we decided to go into public beta with our learning platform and I hope to find some valuable feedback from the hacker news community.
FluxCards is tabbing in an old field of flashcards apps where 30 years ago Supermemo and later Anki and more recently Brainscape came to fame among literally thousands of other, mostly worthless apps (sorry for using this strong word, I consider most flashcards apps that don't use spaced repetition learning worthless). We do so because we believe that spaced repetition learning did by far not yet get the attention from learners that it deserves and if you don't know it and don't like our colors, then by all means please try a competitor's product to see what you've been missing back at school/university.
To get to mass adoption we strongly believe that content creation has to be crowd-sourced and that is why one of the most unique features is shared ownership, allowing concurrent content creation and editing while others are learning. Rich feedback on the use of the content, including feedback on single card performances will help content creators to improve cards to make their cardsets ever better.
Lastly, if you have technical questions, just ask. The most basic might be our software stack (playframework, jquery, bootstrap, touchpunch, mongo) and our collaborative tools (git on bitbucket, kunagi).
