I like your advice but I think there is much more potential in college than high school. In college I have resources available to me that were previously unknown to me, covering every profession, even startups and business.

College was definitely the right choice for me, you should try it and see if it is for you.

At first I was not amused by another URL shortener.

Now I respect you for having the guts to post it here. Props to you.

The only thing that you should add is an optional email address input. Now you can contact the people that are using your app. For instance, if you wanted to email everyone after you rolled out a new feature. Like a new feature that enables your app to email the link you just created to yourself. Maybe is sends another email after 10,25,50,100 visits to let you know.
