You are not tired of Twitter apps. You are tired of someone slapping something together without much due diligence, calling it a startup, and hopping they will get techcrunched, raise venture capital and finally get acquired early on for the low 7 figures. That's what you are tired of.

But you cannot blame someone who is trying to make it out of the rat race. At least they are competing. They will probably build 12 "stupid" apps before finding lucky 13. That last one will be the result of their pointless Twitter apps and honest feedbacks.
