This is a blog post I wrote about my failed side project, hopefully it will help people to avoid the same mistakes I made. Let me know if you have any questions.
Interesting read, may I ask why you chose flask?
Also were you the only person working on this?
Yes I was the only person who worked on this project minus a friend who designed the logo.
I chose Flask because I had some familiarity with it before on a few other small projects I had built and I didn't really need a heavyweight framework (such as Django).
