Some thoughts about what makes an idea worth developing.
Does it help the community?
Is it a platform usable for business?
Will it make money?
Is there a “side door”?
Does it fill a niche?
Will people use it? How do we test this?
Will I use it?
Is it free?
Will I enjoy developing it?
How do we test if people will use it?
