Look man, give kids a break. You want them to be good, but when they build something you give them shit? Who gives a fuck if they put their age on the thread title. Let them put their age in it if will keep them away from the streets (drugs and bad shit) and towards a better life.
When I was 14 years old I started my first business. Man I got so much shit from people. It was awful. I was trying to sell something, but they would not buy because I was too young. Fuck that! But you know who doesnt care if you are too young to sell stuff? Drug dealers. They hire kids to peddle their trash for them. There I was, making an effort not to sell drugs, and people were making it hard for me. You dont know how hard some of these kids may have it. I grew up in a pretty tough barrio, where most of my friends are either dead, in jail, or fucked up. I'm the only one who made it out of there.
So give kids a break. Sure their app might might stink, but who cares? People here talk about fostering creativity and innovation. Shut up and let the kids get a share of the attention.
