Good and very fair question. Firstly, I don't understand why a company would not allow you to pull your data out before closing/be acquired but rest assured if that ever happens to stacknotes (i don't plan on it), I will provide a way to pull your notes out. If enough users wanted it, I might even provide a way to 'backup' or download your notes collection at will. Secondly, i can't answer that question as I haven't really used emacs org-mode (didn't know about it until then) but my main reason would be because of the features which we plan to implement (note sharing, voting etc. https://www.reddit.com/r/learnprogramming/comments/32bjsx/a_...) which I feel will be make us a great alternative.

Again thanks for your message! If you have any other questions don't hesitate to ask!
