Age doesn't reflect on experience. There are 15 year olds that have half a decade of experience developing and there are 30 year olds that started last week.

The people that upvote "I'm 15 and this is my new app..." probably aren't going to upvote "I'm 30 and this is my new app..." but the latter could be a more impressive achievement.

Yep, that's called age fascism.

"Fascism" is a little strong, don't you think? "Discrimination" is probably more appropriate.
