For example assuming 5$ every 1000 impression, with an average of 3 impressions for unique user with 1 million of unique visitors a month you get from adsense 15k$. If there are two founders and bandwidth to pay this means you are making just about to survive.
In this web 2.0 bubble we are living this days I see very few news/technological sites where the business model is advertising and they are really profitable, or I'm missing something? Advertising tends to work only in services where your user base is the average john smith with IE6 clicking everywhere there is a banner. With smart users it gets very hard.
I'm not as experienced as many founders following news.yc but I suggest that if you plan to start a startup you should try hard to get an idea where there is a different business model than advertising, like PRO accounts or things like where there is a straight line binding user satisfaction with your earnings. In our new service we are trying this new model, even if this is also very hard indeed being the world full of free-everything-web-services :)
