I would like to share one quite from Gandhi: Whatever you do will be insignificant, but it is very important that you do it.

People usually don't know what is a good idea / bad idea. Otherwise killer products can be made from market survey, but this is usually not the case.

I second the comment from switch. Also even you just got one user, you are still doing something for good. Start it small, just spend a week or so build a prototype and release it.
