That's part of snapchat's brand, they make all their shit unintuitive, obscure, hard to discover and use. It's supposed to make it so that you feel hip and in the know when you finally discover how to make that mustache appear on your face or make text float in the background of your video.
But of course that doesn't seem to transfer that well to selling hardware.
There is a clear reasoning for this strategy. People and especially press talk more about the product.
Btw, I think Snapchat is quite intuitive. Some features might not be easy to find or to know about. But once you know it is very intuitive and fast to use them. I think it is similar to Vim, if you don't know anything about Vim you cannot even quit Vim but once you know all the stuff Vim is one of the most intuitive editors because UI and most commands are well designed.
You are clearly using a different definition of intuitive from anyone else.
VIM is the least intuitive editor that I know.
Even you are saying that people don't even know how to quit it, how in the world is that intuitive???
If you need to know all the stuff to use it that is by definition not intuitive.
"adjective: intuitive
using or based on what one feels to be true even without conscious reasoning; instinctive.
(chiefly of computer software) easy to use and understand."
I think you are referring to stickiness - which doesn't infer that the product is intuitive.
If you can't use a product right away without help then it is not intuitive by definition. However it doesn't mean you won't like it if taught how to extract value.
For instance it's not intuitive to deep fry a banana and then put salt on it before eating it, but I'm quite certain you will finish the plate once you try it.
