I am actually, the issue here is not that i don't like these projects, but i cannot give meaningful feedback on them... When you develop any sufficiently big project, most of the assumptions and specifications change over time. This is evolution. And what i criticise is, whether it is a good idea to show a half-baked app and make people think that it is useless. I believe waiting a bit more and developing the app and then posting it makes more sense. For all the learning practices, i agree it is very valuable experience, but just let them evolve...
