To be honest it comes off as (at least a little) arrogant in my opinion. It's one thing if I read something along the lines of "This kid is 17 and he's trying to change the music industry" [posted by someone else] because that would be a third party endorsement of your ambition/drive, as well as highlighting your age. It's another if you're boasting about it yourself.

Then again, I'm in my mid-20s so maybe I'm just grumpy that I wasn't as motivated or directed at 17 as you are :)

I'm extremely humble by nature, and the original title took a little bit of nerve to pull off, as did the paragraph. It attracts views though, which is what marketing is about.

Sure it's arrogant (or braggy), but a headline is supposed to catch peoples attention and then it is in the submitters best interest to highlight things that people might find impressive about the submission.

Hah, nothing wrong with that. I'm 17 myself and programming for a bit more than three years now. Currently working on an browser extension for multilingual videos on YouTube. Keep up the good work, looks awesome!

Was this submission's title edited? When did you mention your age?

It said something like "I'm 17 and I made this app:"
