How does 365 data points give your conclusions any sort of statistical significance? Snapchat's numbers are allegedly over 30M, Facebook's are over 1.2B and Instagram's are 150M.

I suggest reading "How to Lie with Statistics"[1]

Edit: I guess that sounded a little harsh. No doubt, Snapchat's growth has been explosive and if this was just another blog-spam post about that fact, I'd let it be. But you're selling a statistical software! I'd expect better from people who know what they're doing. Also, "How to Lie with Statistics" is a really good book, should be required reading for anyone dealing with numbers. Did not mean that as an attack on your product.
