Here are a few obvious criticisms:
1) "Change the world" is a red-herring. There's a lot of very valuable and helpful work that people with a "change the world" focus will miss out on. A lot of people writing craplications believe they will change the world. It's a content-free sound-bite at this point. It doesn't translate into any world-changing behaviour.
2) The value of a thing has very little to do with how hard it is to make. This is a common trap that techies fall into: I worked really hard and didn't get rewarded while someone else spent a few hours and did get rewarded.
2b) If you're going to argue that we're incentivizing the wrong behaviours, well, that's an interesting argument that you didn't explore.
3) Unintentionally, your rant is analogous to the very apps you're criticizing. I.e. it seems you just kind of pooped it out. You apologize for pooping it out, but you don't do the things that could turn it into an insightful or useful article.
Just as various app stores are saturated with crap, news sites are saturated with random half-assed comments that would be funny over beer, but just clog the internets.
