So my camp NaNoWriMo (national novel writing month) project is to write about these two kids who are coding an app together very similar to Tumblr. Basically an app of a live feed of videos, pics, etc. Does anyone know how I could describe the innards of coding for this in layman's terms? Like certain vocabulary, steps, etc? It's a YA novel so I don't want my readers to be overwhelmed with tech speak and either the things I look at are too complicated or skip the steps. I know they would write "psuedocode" and sketch out the interface but past that I'm stuck. Halp?
