Oh, wow, I thought it was excellent, dark humor. As well as the other advice to use an office app like Microsoft Word to get basic English spelling and grammar, consider first serving a smaller audience well in one of your team’s native languages. If an English speaking market is what you are first targeting that is cool too. I would recommend adopting Lean Startup and refocus on what is your MVP and product/customer fit, conversations and experiments.
