However, it's a bit sad to see many one-day projects pop up here and there, which ruins people's believes, and makes it harder for more serious projects to gain attention ("look, yet another stock exchange developer"). Or when someone pops up and says "hey, here is the project which conquered the world" and shows some amateur half-made website. It's fine that it's amateur, nothing is perfect in the beginning, but just don't say that your project already conquered the world.
I think it is more an issue with web development and application development at large. There is little education done with best practices so you end up having people who "learn" php echoing user input everywhere and being vulnerable to SQL injection, XSS, and god knows what else. You can do searches in google that pops up hundred upon hundreds of sites who have SQL statements embedded in their URL >_< At that point you just want to shoot yourself.
