I am developing a web/mobile application.
It is a list and task manager/personal organizer.
I would like to keep it completely free for users.
Moreover, I don't want to show any advertisement on the public area of the website (I don't want to push people off before they sign up).
And it has became my job as I recently resigned from my fulltime job in a company.
What I am doing at the moment is displaying some Google Adsense in the account of the user (after they log in). I am still waiting for the first payment.
I have the feeling that I could do better. I mean, joining better advertisement networks.
