I've got a bad feeling that this question is not appropriate here.. Hopefully you can point me to the right place to ask such a thing (not google though, been there).

I want to create my own product, but for some reason have no ideas, so decided to see what people have already done. I would like to start by myself too. I don't mind expanding, but at later stages when it is absolutely necessary.

Anyway, to give you an example.

There is a guy who created bingo card generation software, then somebody made a wedding planner software and they seem to be doing pretty fine.

I would like to know more such cases to draw inspiration from. Do you know such people or maybe you are one of them? Also, if there are places on the net where they dwell, don't hesitate to tell me :)

Thanks!
