The good use of posting an application on the app store

When you make an app that you think is good and have confident that people would like it, you should post it on to the app store. The reason is that apple is a reliable company, it produces many awesome apps, and will never betray your expectations. But say that you will be posting an app for the school you go too. It may be easier to post it, but you will only get ratings from people inside of school, not out side of school. If you want to be more famous, or to be a better programmer, I would be posting it on the app store to get reviews from world wide, so you can improve on how to be a better programmer or an app maker. Once you become a good programmer or an app maker, the apple company may hire you and now you have a reliable job.
