Quite recently, the CEOs of a few respectable and serious websites, services, and apps hosted an event on reddit that they called Hack4Equality, with "hack" being used as it's literal definition. (The thread can be found here for anyone interested).
There are tons of problems in our world, and they can all be fixed and diluted if people just took the time to help others and cared about humanity.
I think it would be interesting if codecademy hosted an event where they had any user who was interested come up with an idea, brainstorm a problem, etc. and create an application, website, etc. that aided in whatever it is they plan on endeavouring on.
For example, a family in poverty could find an application that helped guide them on how to better save and spend their money useful.
Any critiques and comments are greatly appreciated
